In 2D game development, the creation of sprites is a labor-intensive task. One cost-effective method for increasing the variety of game characters is to reuse the same sprite, but using a different color palette.
This is seen in some platformers, but it most often appears in Role Playing Games and Fighting Games. In fighting games, this is commonly used to differentiate players using the same character, but it is also employed to create "new" characters. In the 8- and 16-bit era RPGs, it was pervasive: because of console limitations, disk and screen space were serious concerns. Palette Swapping was used to create a large variety of different enemies, often using different colors for various power levels. (The most famous group of these are probably the Slimes, topped by the powerful Metal Slime, of Dragon Quest fame).
A more elaborate variation found in 3D games is the Texture Swap, where the textures on the character's uniform are changed, but the actual model used remains the same. While the concept is a little different, these are often called Palette Swaps anyway as they're still easier for developers to make than a full-fledged alternate costume or character. The Head Swap is another tried-and-true technique for making more out of less.
Massively Multiplayer Online Roleplaying Games MMORPGs are often set in a very large world that must be populated by monsters. Palette Swap to the rescue! By changing the size and textures used on the same model, the designers can make many types of monsters from only a few basic meshes. Sometimes even bosses are simply re-textured and are huge versions of weaker monsters.
Some fans of fighting games use the term to refer to characters that use the same animations and move sets, even if the characters look very different. Such characters are also known as "clones". Individual characters may also have a choice of several different colors or costumes (or both).
Palette Swaps are also used in Sprite Comics, where they're known as recolors. They are frequently looked down upon.
For a similar time-saving technique, see Ambidextrous Sprite. See also Colour-Coded for Your Convenience.

In Blaster Master , the Stage 6 and 7 bosses are palette swaps of the Stage 2 and 4 bosses, respectively. The palette-swapped versions were very hard to beat.
The Legend of Zelda: Majora's Mask was designed with this trope in mind: Almost all of the mooks and NPCs, as well as a few of the masks, were ported over from Ocarina of Time. At least the map and the bosses were different. There's also the two elemental versions of Wizzrobe (ice and fire).
In the first game, most monsters came in Red and Blue, with one color (usually blue) being tougher than the other.
In Zelda II: The Adventure of Link, orange was added for weaker variants of enemies, with red being stronger than orange and blue being stronger than red, though with armed enemies the weapons often change with the color (such as the orange variant of the Daira enemy in Death Mountain swinging its axe at Link and the red variant throwing axes at him).
It's even common to palette swap Link for his different tunics. Same style and cut, different color. Like the fire-proof tunic (red), and the inexplicablewater-breathing tunic (blue). It wasn't until The Legend of Zelda: Twilight Princess that the different tunics actually looked different beyond their colors.
Three of the bosses in Wonder Boy In Monster Land have their sprites reused later in the game, Death becomes the Poor God, who steals your gold coins, the Giant Kong is palette-swapped as the Snow Kong, who summons ice cube-throwing Mini-Kongs instead of throwing rocks, and the Red Knight has Blue and Silver variations.
Bugs Bunny Crazy Castle (a port of a Famicom Disk Sytem game starring Roger Rabbit-don't ask) has differently-colored enemies of the same type that behave slightly differently.
Devil May Cry 3: Special Edition plays this perfectly straight. When playing as Vergil and you come to the boss battles against Vergil (the game is usually played as Dante, with the Vergil playability a feature of the Special Edition), the Vergil you fight is dressed in red instead of his usual blue. Apparently it's to give the impression that you're fighting Dante, but the only difference between the two versions is the colour; the boss' moveset remains the same.
In the Rolling Thunder series, the attack patterns and hit points of the Maskers can be determined by the colors of their clothes and hoods.
Steve's jacket in Shatterhand turns from green to red when he buys the double strength Power-Up.
Beat Em Up
Cyborg Justice pretty much embodies this trope since the player character can choose torso, weapon and legs which are interchangeable and used by virtually every other cyborg in every level at some point including bosses. The only unique enemy in the entire game is the end boss who is a giant brain. If you play with two players, then player 1 is primary gold and player 2 is primarily purple.
The arcade version of Double Dragon, in addition to the two player characters (Billy and Jimmy Lee), has a set of three enemy mooks (Williams, Rowper and Abobo) that it uses for every stage, but with a different palette each time, along with the occasional black variants. The two bosses, who are themselves head swaps of other characters, reappear in the final two stages as well (in particular, the third boss is the first boss with green skin). The only enemies who don't have palette swapped variants are Linda (who wears the same purple outfit in all of her appearances) and Machine Gun Willy (the final boss).
The character designs in Fear Is Vigilance are basically limited to three: male, female, and Marcy in disguise. Everything else is palette swapping.
Final Fight mostly averts this by making variants of the same enemy head swaps as well, but there are a few notable exception: Roxy is just Poison with orange hair and everyone in the Andore clan are identical except for the colors of their clothing (lavender for the standard Andore, red for Junior, gold for Father, black for Uncle and blue for Grandpa). There are also red-clothed variants of Holly Wood who carries Molotov cocktails instead of his usual knives.
Final Fight 2 for the SNES has a cheat code that allows both players to use the same character if selected, distinguishing the second player with a different palette.
The GBA version of the original game, Final Fight One, also allowed two players to choose the same character after defeating a certain number of enemies.
Golden Axe has a huge amount of palette-swapped characters, from the mooks to the bosses to the Bizzarians to the energy-replenishing elves.
The arcade version of Ninja Gaiden (aka Shadow Warriors) features six stages, the same four staple adversaries, a few novelties here and there, three distinct end of stage bosses, one final boss, and a different palette for each stage. There are also ninja mooks who are just palette swaps of the player characters (who are already themselves palette swaps of each other).
River City Ransom recycles the same enemy gang of nine members by changing the colors of their t-shirts, as well as modifying their stats and attack patterns.
In the "Dueling" mode featured in the sequels, the second player is assigned a different palette if he chooses the same character as the first player.
In the first game, Onihime and Yasha (aka Mona and Lisa), the twin bosses in Round 5, were both palette swaps of Blaze but with a green outfit instead of red. In Round 8, they appear one more time with a dark purple outfit. When the twins returned in Streets of Rage 3, they were given a unique design.
In the third game, the boss of Round 3 was a robot copy of Axel, only difference was his gloves were purple instead of red so that players who played in co-op wouldn't attack each other by mistake if one of them was playing as Axel.
The Foot Clan ninjas in Teenage Mutant Ninja Turtles: The Arcade Game (and its sequel, Turtles in Time) come in numerous colors in addition to the standard purple variant from the 1980s animated series. The Foot Soldiers are color coded to indicate their weapons of choice. For example, the white Foot Soldiers attack with katanas, while the orange ones wield boomerangs.
Clayfighter also did this for the 'fight the character you're playing as' scenes.
The original Eternal Champions game notably didn't have any. The sequel had palette swaps, head swaps and even leg (Riptide has Jetta's stance and Shadow's legs) swaps.
When Bandai released Gundam: The Battle Master 2 in the US as Gundam Battle Assault, they replaced one of the mecha with the titular Gundam from Gundam Wing in order to cash in on the show's then successful run on Cartoon Network. Despite going through the trouble of making a separate sprite for it, however, they gave it the same moveset as the Zeta Gundam. Further annoying is the fact that its super move involves grabbing the opponent instead of shooting its BFG.
Mortal Kombat was one of the most notorious examples of this trope with its "Palette Swap Ninjas". There was an increasing number of ninja characters (Scorpion, Sub-Zero, et al.) of three basic types — male, female, cyborg — in the games, almost all of whom used the same basic set of sprites, with the color scheme altered to match the individual character. Illustrated here◊. With the advance of video game technology, in Mortal Kombat 4 and beyond the various ninjas have been redesigned to avoid this, however - particularly Reptile and Rain.
Mortal Kombat Trilogy was seriously getting short on colours for male ninjas: Classic Sub-Zero (blue), Scorpion (yellow), Reptile (green), Rain (purple), Noob Saibot (black), Ermac (red), and Human Smoke (gray). In mirror matches, the twin was usually a slightly different shade of the same colour.
Note that the default ninjas in all four 2D Mortal Kombat games for the arcade (counting the original version of 3 and the Ultimate edition separately) actually had different fighting stances from each other, so they were not full-fledged palette swaps. However, the hidden variants played this straight.
In the first game, Reptile used Scorpion's fighting stance.
In Mortal Kombat II, Smoke uses Reptile's stance, Noob Saibot uses Sub-Zero's (which would foreshadow his identity as the original Sub-Zero gone evil), and Jade uses Kitana's (setting up their relationship in 3 quite nicely).
In Mortal Kombat 3, Robot Smoke uses Sektor's stance. Since none of the "human" ninjas were in the third game initially, Noob was instead a palette swap of Kano.
In Ultimate, all three female ninjas used their own stances; Noob, Ermac and Masked Sub-Zero used Scorpion's; while Rain and Human Smoke used Reptile's.
In Trilogy, Khameleon and Chameleon's stances would reflect who they were currently copying.
Epic Megagames' fighting game One Must Fall makes extensive use of palette swaps. The game has 11 distinct (sprite) models of robots, but many more colour-schemes, all of which are achieved by changing parts of the game palette. In tournament mode, you can customize your robot's colour-scheme in three areas, and the game provides you with 16 colours to choose from.
There is an external free tool that lets you create your own tournaments, and you can give the computer opponents anything you like for their colour-schemes by editing the palette of the picture to go with their character.
Primal Rage does this for the stages where you're fighting the character you chose to play as. Does have a benefit there as it helps you stay sure of who's who. In addition, Blizzard and Chaos seem to be palette swaps of each other, as do Sauron and Diablo.
A famous example of the skin-color aspect of this trope was the character Nakoruru from the Fighting GameSamurai Shodown. The swapped palette used on her portrait in the character select screen made her look like her own Evil Twin. Naturally, the idea quickly entered Fanon, and Samurai Shodown V actually turned "Evil Nakoruru" into her own character.
This was most likely also a result of SNK actually intending the "Slash/Bust" division to represent good and evil sides (or at least different personalities), never being able to pull it off, and ultimately simply deciding to just make a couple variant characters and call it a day. The other, BTW, is Rastesumaru, a much, much different version of Haohmaru. (He has purple skin, for one. He's completely psycho, for another.)
There are at least 18 palettes for every playable character, some of which are Official Fan-Submitted Content and many, many of which are referential. More distinctly, it also has an alternate palette for its story mode boss and a shifting rainbow palette for one of its characters, Double.
Initially just an April Fools character, Fukua, a clone of their pre-existing character Filia was created as a jab at the popularity of palette swaps. Despite being a palette swap, she has a very different moveset, although it reuses Filia's assets, for example by making one of her projectiles shoot a ghostly clone of her, and giving her two command grabs that have the same animation as her normal grab but different startup times and damage. Also, nearly all of her palettes are referential to other games' palette swap characters.
In the Fighting GameSoul Calibur, the character Kilik is a Palette Swap — in the shared motion data sense — of Seung Mina. (This is explained in game by both characters using the same fighting style: Ling Sheng Su.)
Hwang is an odd case. In the original Soul Edge, he was a "motion swap" of Mitsurugi for Korean localization. In Soul Calibur, he became a swap of Xianghua, but shared some kicks with Seung Mina. By Soul Calibur III, he was the representative of the Chinese Sword style.
Actual palette-swaping entered the Soul Calibur series with Custom Characters, as well as the ability to alter the colors worn by the standard fighters. Meanwhile, Tekken 5 offered color choices along with custom items as unlockables.
The Tekken series of games has had THREE. Mokujin (Tekken 3) and Combot (Tekken 4), which randomly emulated all the characters fighting styles, one per round, and Unknown (Tekken Tag Tournament) who looked sort of like Jun Kazama, but could only emulate about 15 or so characters out of the 30+ available (in addition to the resemblance, she always started with Jun's moveset). However, pressing down on the right stick on the PS2 controller (R3, as it is) would let you change fighting styles on the fly instead of having to tag out and back in all the time.
Namco's games also did tend to have fighters who shared many moves. Examples include the Jack 'clones' (ironically, of the ones with that label, only Kuma's been in all the games in some playable form), as well as characters with similar styles in game (Anna and Nina Williams, King and Armour King, Yoshimitsu and Kunimitsu). They're working on making each character more unique, though.
Tekken 3 introduced a new generation of fighters who had stances and fighting styles taken from previous characters that had supposedly killed off. So Hwoarang was meant to be a replacement for Baek, Bryan Fury for Bruce Irvin, Xiaoyu for Wang, and so on. When the predecessors returned in future installments, Namco altered the various characters accordingly to prevent redundancies. Tiger Jackson was also a Palette Swap of Eddy Gordo, even though they both debuted in the same game.
Namco has stuck to this tradition. Christie from Tekken 4 was introduced as a replacement for Eddy, while Asuka Kazama from Tekken 5 was meant to be a replacement for her deceased aunt, Jun Kazama.
When the Street Fighter series started featuring same character matches (beginning with Street Fighter II′: Champion Edition), the game changes the palette of one player to distinguish it from the other. Depending on the character, some alternate palettes will simply change the color of the character's clothing (i.e. Ryu's gi and bandanna), while others (such as Dhalsim's and Blanka's) will change the character's skin tone to improbable colors such as blue or grey.
Super Street Fighter II in particular features eight palettes for each character and each player chooses which one they want to use on the character select screen depending on the button pressed. However, the control panel only has seven buttons for each player (six attack buttons and Start), so the eighth palette can only be chosen by pressing any button and keeping it depressed for a few seconds.
Super Street Fighter II Turbo gave all of the returning fighters a new default palette, while the original default palettes are now used by alternate versions who retained their moveset from the original Super Street Fighter II. Moreover, these alternate versions of the characters have their own alternate palettes as well.
In the arcade version of Street Fighter Alpha 2, the character's palette changes depending on whether the player is using the Manual fighting style (three-level Super gauges) or Auto (one-level gauges, simpler inputs for Super Combos and Alpha Counters and auto-blocking). This was carried over to Alpha 3, when the fighting styles were expanded to A-ism (Alpha-style), X-ism (Super Turbo-style) and V-ism (Variable Combo-style).
Some versions of Alpha 2 (specifically the U.S. arcade release and the Zero 2 Alpha released in Asia) allowed players to control alternate versions of certain characters such as Zangief, Dhalsim, Ryu, Ken, classic outfit Chun-Li, Sagat and M. Bison who used their movesets from Street Fighter II Dash and had alternate color schemes. Evil Ryu and Shin Akuma were also palette-swaps of their regular counterparts.
In Street Fighter III 3rd Strike, there are a total 13 palettes for each character (except for Gill, who only has two). There are six standard palettes chosen by simply pressing any of the attack buttons, six alternate palettes chosen by holding Start and pressing any of the other buttons and a hidden 13th palette selected by pressing LP+MK+HP.
Bioshock only had a few distinct Splicer models, with palette swapping used (mostly on their clothes) to make them slightly less identical.
In Conduit 2, the models of the soldiers are all the same, but the armor they wear is chosen randomly.
Doom, on the other hand, use palette swaps mostly for changing the uniform color of different players in multiplayer mode (the green armor becomes indigo, brown and red for players 2, 3 and 4); however a variant of palette swap is used for one of the monsters: the Spectre is a Demon whose sprite's shape is replaced by a zone of transparent static. In Doom 2, a palette swap was used to create the Hell Knight from the Baron of Hell; however both sets of sprites are present in the game's data and the two are treated by the game as totally separate enemy types, other than being hard-coded against the usual rules for taking and responding to friendly fire.
Doom RPG, however, had "classes" of enemies that changed palettes according to their type and subsequent difficulty.
BUILD Engine games, such as Duke Nukem 3D and Shadow Warrior, make use of palette changes on sprites and surfaces for a number of uses.
A number of surfaces which basically look the same, but have something a different colour (such as a row of tiles on a wall) use an internal palette change to provide more graphical variety without needing to include more textures.
Coloured lighting uses a palette change over the whole palette of anything in the area in question.
The ever-common alien Troopers and Captains in Duke Nukem 3D use the same sprites, but different internal palettes. The base sprites use blue for the uniform, but the Troopers use a palette that replaces it with green and the captains use one that replaces it with red.
On a similar note, the different colours of the trousers on the player sprites in multiplayer games are the result of palette swaps.
Putting the same palette used for blue light onto a sprite such as a weapon or switch in the level editor will (at least for Duke Nukem 3D) make that sprite only appear in deathmatch games.
Different palettes on special sprites which control level functionality can have various effects, ranging from simply changing the colour of a light to making a teleporter that doesn't show the usual teleporter effects, to determining what kind of enemy teleports in.
Palette swaps combined with translucency are also used to give the enemies shadows. Squash a copy of the sprite vertically, put it on the ground, put an all-black palette on it, then make it translucent. Some levels also use all-black translucent palette swaps of sprites to add nice shadows to certain areas.
Then there are user-made levels which give oddly-coloured enemies via palette swaps just for the fun of it. Some sadistic authors put the all-black palette on the enemies and make them transparent. Great, now you're fighting almost-invisible aliens.
The first Halo does this with the Grunts and Elites. You can tell how powerful these enemies are simply by their color. The in-game explanation is that their armor is color-coded by rank. The subsequent games also do this, but also add fancier armor for certain Elite Mooks.
The Marathon series used palette swapping extensively. An alien's uniform color denoted its rank, while a human's denoted his department.
Left 4 Dead 2 has the laser sights and special ammo using the same inworld model, but with different textures.
As well, to increase variety, the common infected use similar models, but have different skin/clothes colors.
PAYDAY: The Heist has the Clown mask model recycled for other masks and use different textures, namely the Golden and Secret masks.
Dallas' Vyse mask is also the Clown mask retextured while Hoxton's Vyse mask is a different textured version of his Beeef mask. Chain's Vyse mask is the same model as the Moderator and Overkill/Dev mask and those two masks are palette swaps of each other. The Alienware masks are a single model with different textures as well.
Perfect Dark for the N64 had Joanna (the main character) and her head-swap Velvet (controlled by Player 2 during Co-Op Mode). Since they were both Carrington Institute agents, they both wore the same uniform.
Team Fortress 2 is the epitome of palette swaps - not only are the classes identical save their team colour, at least three levels contain what are basically palette swapped bases, with changed materials and propaganda posters. Not only that, but the September 30, 2010 update allows players to paint their hats.
Player-created maps are sometimes guilty of this as well. There are several variations of 2fort with the exactly same layout, but one is at nighttime, etc.
Pretty much every Capture the Flag map is literally just two bases that are exactly the same except they're mirrored and palette-swapped, with a few paths in between that connect them.
There was actually a contest to "dress up" a Valve-designed map that only had basic geometry. The winners of which were later used for the Mann Manor Halloween update.
Several other maps also had Halloween versions.
Referenced in the Developer's Commentary. They noted that, for balance's sake and outside of Attack/Defend maps, they had to make both the RED and BLU bases identical, as otherwise it would offer a tactical advantage to one team over another. To help players not get lost however, they had a strict set of materials, colors and styles they could use for each side; Red was wooden, red (obviously), and used sheet metal and hay. Blu, on the other hand, used concrete and industrial pressed metal, as well as having an overall blue tone. Red was also suppose to be more rustic while blu was more industrial design-wise.
Turok 2: Seeds of Evil has a few of these; the Cave Worm is a giant version of the Swamp Worm, the Fireborn is a firey version of the Endtrail, the Blind One Sentinels are a palette swap of the Flesh Eater Sentinels, and the Trooper is a palette swap of the Mantid Soldier.
Roguelike games such as NetHack use standard ASCII characters in place of actual graphics, so using different colors is the only way to have a large number of distinguishable objects or creatures. Roguelikes can usually only support 16 colours due to graphics rendering limitations in early hardware, giving a potential maximum of 2040 unique enemy symbols.
The Game Boy Color, Game Boy Advance, and the Super Game Boy (for the SNES) allowed users to palette-swap original Game Boy games entirely (at least the ones that weren't designed to take advantage of the color features of the devices).
Some old games palette swap everything after each level to give the player a sense of progress. Desert Falcon for the Atari 2600 looped between about eight colors as enemies moved slightly faster, so even field below changed from yellow to green to pink. Even the NES version of Tetris does this as the game's level increases.
Hack And Slash
The Diablo series is infamous for this, frequently featuring the same enemy 3-5 times by recoloring and renaming it.
One of the first games to use Palette Swaps was Pac-Man. Also Color-Coded for Your Convenience as each a different way of chasing the player. note Namely: Blinky (the red ghost) actively chases you, Pinky (the pink one) tries to maneuver around you and then cut off your path in an ambush, Inky (the light blue one) takes an erratic pattern that involves both where Pac-Man is going to be and Blinky's location, and Clyde (the orange one) acts like Blinky but runs for the bottom-left area if he gets too close.
Being the second game Luigi ever showed up in, Wrecking Crew once again has him as a recolored Mario.
City of Heroes makes frequent use of Palette Swapping in uniformed enemy groups such as Arachnos, where different ranks (and sometimes entirely different classes!) of enemies share the same uniform with a modified color scheme. I.E. Psychic Fortunatas wear red versions of the normal Night and Blood Widow uniforms. Arbiters (who are the highest ranking members of Arachnos, said to be above even the four Archvillains in terms of authority) wear shiny versions of the Wolf Spider uniform.
Also interestingly enough, a player using the Mission Architect can actually palette swap preexisting enemies! Even AVs! And, of course, due to the game's customization system, the vast majority of models use one of three basic animation sets anyway.
Dynasty Warriors: online. Given that all mooks on different sides are simply palette swaps of each other, but the custom outfits can also be. You can individually "dye" each item so that they change color, There are three different dyes that give you a unique color for each one. the Weapons also change color when you add an innate element to it. They will take on a basic color for the element, but other colors on more complex looking weapons will change to fit the theme of the main color (like gold might change to silver). You have ice (blue and silver), fire (red and gold), wind (green and silver), Lightning (yellow and bronze), vorpal (purple and bronze).
Faction ship models in EVE Online are their base ships with different color schemes. This is true of their pirate counterparts as well.
Most fluffs are recolors and/or upscales of one another with minor details changed.
Kat's Kokeshi Doll and the Kokeshi Collectibles are palette swaps of normal Kokeshi Dolls.
Gift Boxes from the 2008 Christmas event were Christmas-themed recolors of Flying Giftboxes.
Lightning Bugs, Shockroaches, and Deathroaches share the same base model.
Landstriders are green and black versions of the Walker.
Outlaw Wolves are green Outlaw Pups.
Phantasy Star Online plays this straight for their non-unique weapons. All basic weapons only differentiate in color and name to denote how powerful they are (from weakest to strongest, the colors are green, blue, purple, red, and yellow.)
Phantasy Star Universe takes this a step further. In addition to non-unique weapons differentiating in color, both non-unique and rare weapons have a bland-looking "Kubara" version that usually has worse stats, but offers larger grind bonuses.
RuneScape Classic used this trope: the game environment was 3d but the enemies were 2D sprites, so enemies such as "thief" "man" and "farmer" were often simply palette swaps of one another. Also, the customizable player character models could be considered this as well.
SD Gundam Capsule Fighter has the "-U" rank units, "User-Created" special units from the Korea server who color certain units (all but one being a C-Rank) and are granted different skills and stats, usually having the skills make up for the weaker stats.
There are thousands of different types of "mobs" (monsters) a player can encounter, but only a couple hundred different animated models. Most of the variety comes from putting differently-colored skins on the same model. For example, the grizzly bears in Elwynn Forest or Dun Morogh use the same models as the polar bears in Icecrown and the disease-raveged bears in the Western Plaguelands, and the same animations. They just use different-colored skins and, in some cases, enlarge or shrink the base model.
Blinx: The Time Sweeper does this with at least two pairs of bosses. In one, the first monster is yellow; later, you face an identical red counterpart.
Averted by the main characters in the arcade versions of Contra and Super Contra, which used different sprites for Bill and Lance (Bill wore a white tank top, while Lance was shirtless). Due to hardware limitations of the NES, their versions of both games used the same sprite for Bill and Lance, changing only the color of their pants, making Bill the "blue guy" and Lance the "red guy". Oddly enough, Contra III: The Alien Wars for the SNES followed this convention as well. In Super C and Contra III, the red colored enemy soldiers are usually the ones who actually shoot their guns. Also, the four main characters in Contra 4 (Bill and Lance, and their "counterparts", Mad Dog and Scorpion) are all palette swaps of the same sprite, with no real playing differences between them. This was due to a 4-Players Mode that was Dummied Out from the final version of the game. The extra characters (Probotector, Sheena, Lucia, Jimbo/Sully) all happen to have four selectable color palettes each as well.
Lampshaded by Cranky Kong in the Game Boy Advance version of Donkey Kong Country, after a boss battle with "Really Gnawty", a recolored version of the first boss, "Very Gnawty", which is itself a big version of a normal enemy called "Gnawty". The quote at the top of the page comes from after defeating Master Necky Sr., a palette swap of Master Necky Jr.
In the SNES version of Donkey Kong Country 3, there was a hidden code to give Kiddy and Dixie Kong different colored clothing. It didn't affect the game, but the alternate colors looked cooler than the regular colors.
Donkey Kong Country 3 also had Koindozers, which were similar to Klobbers from the second game, but were a palette swap of Koin (a Kremling that used a DK Coin as a shield). The rest of Donkey Kong Country follows suit with different coloured Kremlings and other mooks, this gives away whether or not some are Demonic Spiders (the grey Klobbers that rob you of lives) or Invincible Minor Minions (Red Zingers and Nigh Invulnerable Green Zingers). Red Zingers could only be killed with Squitter's webs (unreliable because Squitter is only in a few levels), while Green Zingers could be killed with barrels as well.
This is used heavily in the TurboGrafx16 game Dragon's Curse, where eventually you will run into three colors - red, green, and blue - of every enemy in the game.
In Kirby and The Amazing Mirror, you get three palette-swapped helpers and the ability to change your color. You can change colors in Kirby Squeak Squad as well. Many of Kirby's hats for his copy abilities are palette swaps of each other, including bandannas, backwards baseball caps, and crowns.
Kirby Super Star uses different palettes for the Helpers and their enemy counterparts (with the exception of Wheelie). Of note is that the Helpers' colors are in fact their standard palettes as Mooks in other Kirby games. Milky Way Wishes adds a third palette to most (all?) enemies, and the Helper to Hero mode in Kirby Super Star Ultra adds a fourth to their playable versions. Several of the bosses reappear under different palettes, as well, though they aren't acknowledged as different bosses.
Several of the Metroid games have enemies who are palette swaps of each other, though Super Metroid mixed it up by making some common enemies larger instead.
The original Metroid on the NES had the varia suit just one of the power suit, which didn't have the "puffy" sleeves.
The Metroid Prime series uses this fairly often. For example, the Phaz-Ing in 3 are reskins of the Inglets in 2, the Mechlopses in 2 are reskins of the Triclopses in 1, 2 used reskins to create "Dark" versions of many enemies, and so on. In a somewhat odd aversion, the Bombus from 1 were reused as Luminoth drones in 2 with no changes to appearance and only the most minor alterations to activity. Even the weapons get this; the Ice Beam and Plasma Beam in Prime show up in Echoes slightly reskinned as the Dark Beam and Light Beam, respectively. The scan for the Metroids in Echoes even mentions that they're vulnerable to the "freezing effects" of the Dark Beam.
Mickey Mousecapade for the NES has a seasonal-themed level where you walk through the woods in all four seasons, with only color changes to represent the seasons. Purple leaves for the trees in spring, green leaves for summer, brown leaves for fall, and white leaves along with white "grass" and "ice" replacing the path for winter.
The very first Rayman game had the very first boss and second/third (depending on player's choice) one being palette swaps of each other - originally. However later editions of the game infamously removed the palette change partially or completely, leading many players to believe they were fighting the same character again - which absolutely did not make any sense in context.
This happens again in Sonic Advance 2 with Amy who is nothing more then a palette swap of Sonic with some minor changes made to animations and a lack of two mostly useless moves and a larger air attack radius.
The character running sprite from the Sonic the Hedgehog 2 Special Stage is the same no matter if you're playing as Sonic, Tails, or Knuckles when locked-on to Sonic and Knuckles. Only the head (and Tails' titular appendages) are changed - the body is palette swapped.
Spyro The Dragon provides a 3D example. About midway through the game, Spyro encounters wizard enemies that shoot lightning bolts and wear green robes. Later on in the game, he encounters the same exact enemy model, except these wizards have blue robes and the additional ability to animate suits of armor.
Shows up in a Hero's Tale with Ember and Flame who use the same basic model of Spyro but slightly changed and when you unlock them as costumes no new voice clips for Ember the girl.
In Super Mario Bros. 1, Red Koopa Troopas are smart enough to turn around when they come to a ledge, while Green ones walk right off, even into a Bottomless Pit. Water and lava used the same sprite with different colors. It wasn't until the All-Stars port that gave water and lava their unique sprites. Fire Mario is a palette swap, and star power switches through palettes rapidly. Mario's brother Luigi also began life as no more than a palette swap, but he later evolved into the taller, thinner look that he is known for when the Japanese game Doki Doki Panic was ported to the west as Super Mario Bros. 2. This differentiation between Mario and Luigi has stuck ever since, as did the alteration of their shirt and overall colours (switching in SMB2 from red/green overalls and blue shirts to the more natural blue overalls and red/green shirts). This was parodied in Paper Mario: The Thousand-Year Door: Mario could change his shirt and hat color to green by wearing the L Emblem badge. Despite this being the only change, the president of the Luigi Fan Club (and no one elsenote except for Pennington, but he mixes them up even when Mario is wearing red...) can be fooled when Mario uses this badge. In fact, this is how you solve one of the troubles.
In Super Mario Bros. 2, similar to the Koopa Troopas of SMB fame, there are actually two colors of Shy Guy, although the two colors are closer. The difference is exactly the same: Shy Guys in pink turn around when they hit edges; Shy Guys in red walk right off. The three kinds of Birdo have more strikingly different colors, and they indicate what they spit: eggs only, fireballs only, or both. Snifits come in even more colors with a wider variety of behavior, from walking off of cliffs to turning back to spontaneously changing directions to jumping and firing more rapidly. Also, the flicker of damaged enemies or things about to explode changes based on what character you're using. This is because all sprites on an NES screennote Actually, on a horizontal line, but SMB2 can't actually take advantage of that since the throwing things play mechanic means sprites could end up ANYWHERE. can only make use of one of four sets of three colours (chosen from a palette of 53). In most games, the player character gets one of these sets, and in SMB2, each player character uses a unique colour set. But since you don't want enemies changing colour based on which character you're playing, that only leaves 3 sets left for every single other sprite, which includes vegetables and pretty much anything else that has to move around the screen.note Though note that it's moving around the screen that matters here: tiles - the other type of object used in NES games - get their own four colour sets, and can be animated by flicking through a series of tiles, but they have to fit into the grid, and the NES can only have a limited number of tiles ready to use at the same time. You can't change the colour scheme assigned to the enemy without changing all other enemies and whatnots using that colour choice, but you can switch that particular enemy's sprite to one of the other colour sets, and the player character's colour set is about the only one that's at all predictable.note By the way, this restriction actually determines what vegetables are used in a level. The new vegetables seen in the battle against Wart use his (or his bubbles') colour scheme, for example.
In Super Mario Bros.: The Lost Levels, the Poison Mushroom is black with brown stains, almost an inverse to the normal mushroom (brown with red stains). it gained a more distinct appearance in later versions of the game to make the game slightly less frustrating.
Paper Mario had different colors of Shy Guys seemingly just for variety; however, most color changes in enemies do indicate an increase in difficulty. Red and Blue Goomba, the minibosses for the Prolouge, have slightly different HP, for example.
Super Mario Bros. 3 had brown Paragoombas that hopped along the ground, and tan Paragoombas that actually flew around, dropping Mugger Micro-Goombas. Gold Cheep-Cheeps and green Parabeetles were among the Dummied Out enemies.
Super Mario World expanded on this by giving us four colors of Koopa. The original two colors retained their behaviors, while Blue and Yellow were a little different. Take note that a Koopa wears shoes that correspond to their shell color, which can change if a Koopa enters a different colored shell. Additionally, while Yoshi had a shell in his mouth that was a different color than green, he would have a certain power. We also see different colored Yoshis right off the bat. Yoshis other than green ones add the corresponding shell color's power as long as they have shells in their mouths, so you could actually have two at once. There's also a Koopa climbing into a Yellow Shell that would become a color-flashing and resilient Koopa that relentlessly chases you down, and a Koopa stomped out of a Blue Shell would become a shell-kicker. The caped, flying Koopas are from red, green, and blue shells.
Played for laughs in Distorted Travesty, with the Sentinel and the Palette Swap Sentinel, the latter of which is slightly tougher. Jerry and Jeremy declare their opinions about how cheap and uncreative this is.
Forza Motorsport uses a bit of this with its cars; some manufacturers have what is essentially two cars that are exactly the same sold under different brands. The standard Acura NSX and Honda NSX are prime examples, being identical except for the badges, default colors, and which side the steering wheel is mounted on. Purpose built racing cars by the same manufacturer hit this as well, as many of them are based on the same car, with the same internals, but with the livery and maybe the default tuning setup (such as suspension height) changed; once the player adds his own livery, the difference between them is almost nonexistent. Some cars also have performance versions, which are generally the same thing but with slightly different bodywork and some more power (such as the standard Lamborghini Murciélago and the Murciélago LP 640).
Gran Turismo 5 - Famous for having around 40 versions of the Nissan GT-R / Skyline, though many are separate generations (and thus, have different bodywork and internals).
Played straight at the Vauxhall and Opel car list. They have the same car list, the difference being the brand. The reason is that Gran Turismo 5 ownard, all region-exclusive cars are in every region game.
Real Time Strategy
Pikmin does this with the Bulborb subespecies. There's red, white, black (Bulbear) and orange.
Sacrifice has five sides with 9 unique units each. A few of these 'unique' units are palette swaps. The manual explains all of them: Some are the same creatures that defected to the other side, and were granted different powers by their new god. Or were killed by Charnel and raised as The Undead.
Star Wars: Empire at War: Forces of Corruption example: Grand Admiral Thrawn's flagship, the Admonitor, is a blue version of the Accuser, Captain Piett's ship from the original Empire at War, but with a different special (all Star Destroyers have a tractor beam special).
As noted above, the Warcraft franchise does this a lot, particularly World of Warcraft, which is notorious for reusing character models and animations. Although it's understandable why a polar bear would share the same model as a grizzly bear, it's slightly jarring when you encounter a boss like Murmur who is clearly a copy of Ragnaros with only minor changes. Even in the RTS games, some units share the same model as another one. Like how a tinted Acolyte model was used for a "Fallen Priest" and "Heretic" in the Orc campaign for Reign of Chaos. But some are more subtle like how Harpies use a modified Gargoyle model.
If you lacked 3D rendering skills, this was what you were reduced to doing for custom maps with custom creeps in Warcraft 3's World Editor. The game itself gave you some flexiblity in changing their sizes and tinting them different colors, but apart from that you had to work with what was shipped.
In Command & Conquer: Tiberian Sun and Red Alert 2, the 3D models of each units used a palette with some "remap" colors, which were assigned to the team colors. The rest of the palette didn't change. In fact, the entire franchise does that, and the first two games had unit sprites in common: The first two games made no attempt at a distinction between the basic infantry and some of the buildings. This even carried over games, as the Soviets had pretty much the same tanks and infantry as GDI, except they were red as opposed to yellow. The Allies and Nod had some tiny variations, since they changed the sizes of some of the tanks to differentiate them, but otherwise the Allies was a palette swap of Nod.
In the StarCraft campaign, special units were often assigned a different team color so the player could tell them apart from their normal counterparts. Only Kerrigan in her Zerg form had a completely unique character model.
Incidentally, the way this was done (put the "hero" unit on another team and set that team/unit to "rescuable" status, meaning that you gain control of it when you get close enough to it, then put it right next to your starting units) also led to the unit's appearance being accompanied by a short audio jingle, as if to say, "I'm important, so don't go getting me killed, kthx".
Dance Dance Revolution character dancer's outfits are palette swaps of each other. In Hottest Party 1, and each new character introduced in Hottest Party 2-3, gets 1 outfit in four colors. I don't know if the PS2 characters outfit's do the same thing, but it's possible. One palette can make a character look great. Some, on the other hand... http://www.konami.jp/bemani/ddr/jp/gs/hp/basic/chara.html# (hint, hover over Rena's yellow outfit. ick. her green one is ick too.)
Most characters in pop'n music have palette swaps that can be selected by pressing a yellow button on the character select screen. Sometimes the character's palette-swapped form takes on a different name (i.e. Vic Viper's swap is called Lord British), and sometimes you'll get a different character altogether.
Role Playing Game
Another Squaresoft RPG, Chrono Trigger, was brutally honest about its use of palette swapped enemies. The imps that you fight early in the game are named "Blue Imp" and "Green Imp" respectively, and the bestiary in the DS version differentiate between the two versions of the "Hench" monster by designating them (Blue) and (Purple). Other palette swapped enemies are given unique names, however.
Cthulhu Saves the World switches palettes on several early goons to be used again later. The trope is called out sarcastically in one monster's description, "Definitely not just a palette swap.".
Most wizard enemies in Dink Smallwood mods are darker recolors of Martridge, the wizard from the original game. Occasionally one of the other characters or monsters gets color-swapped, such as the ice-blue pillbugs in Dink Smallwood's Christmas.
The Fallout series uses palette swaps for certain subtypes of non-human creatures, as well as giving some the Underground Monkey treatment with different models and abilities.
The Final Fantasy games feature a lot of these, including Underground Monkeys. Perhaps the most noticeable example is Final Fantasy X's Monster Arena, where all the bonus monsters are simply previous enemies and bosses colored differently (save for Neslug).
Final Fantasy VIII is just about the only game that does not use palette swaps in copious quantities, and even that game has Ultima/Omega Weapon and Elnoyle/Elvoret as swaps. This is justified in that Elvoret was an Elnoyle residing the tower and Omega was Ultima reincarnated by Ultimecia.
FFVIII was the only game not to actually need this because the monsters leveled up with you. The other games had to make palette swaps from necessity.
Final Fantasy IX had just about as little of it as possible too. The only palette monsters are the friendly monsters, the black waltzes and the crystal versions of the four chaos bosses. Mind you, while the -enemies- were almost all unique, the NPCs could be another story (though they too were often more varied than expected).
Final Fantasy X-2 at least tries some mild deviation, by making its palette swapped baddies progressively bigger. Although the game still suffered this trope for a few enemies, including the Final Boss; the final boss is basically a copy of the main character from Final Fantasy X in different clothes and uses the exact same battle animations, right down to his critical HP and KO animations!
Final Fantasy XII still uses Palette Swaps, but rely on them a lot less than the past games did. For example, dragons and wolves will still come in different colors, but will also have other features added to make them different from their weaker counterparts, such as spikes on the skull, sport flaming eyes, being larger than the previous monsters, etc. However, the animations are still recycled for all monsters that are in the same family tree. There are mentions of migration and evolution of creatures occasionally in the lore, though, which explains a good few examples... but not why the wolves' basic attack is an uppercut performed with their snoutsnote since they use the same animations as the Hyenas, which have a sharp horn on their muzzles that the wolves lack.
Final Fantasy XI has similar explanations for why monsters of the same family had such bizarre separations across environments. On the other hand, FFXI barely even uses palette swaps; including many 'Bosses' (rare monsters referred to as NM, although mostly not storyline related) using the same sprites as the regular mobs that surround them (although occasionally with an inflated size). This was particularly bad where, for quite awhile after they were introduced, five of the most powerful monsters in the game (at the time of their release) used the same models as far more mundane creatures. They've since been reskinned, but still use the same base models.
In Final Fantasy XII Revenant Wings, all the regular summons (bar the ones like Levianthan, Ifrit, and so on), are palette swaps of each other, so that like the above example the player can tell them apart.
Fire Emblem Awakening: All of your allies' outfits for their classes tend to either be blue or have blue lining. There are a few exceptions, however:
In the true tradition of the red/green cavalier duo, Sully and Stahl, have red and green cavalier outfits, respectively, and the red and green lining is used for their paladin and great knight uniforms.
Kellam, an armor knight, has orange lining on his uniform. Like Sully and Stahl, he keeps that color for his great knight outfit; ditto goes for Sully's future daughter Kjelle, only with light purple instead.
Lissa has a yellow dress for her cleric and war cleric classes, and she gets a green and yellow sage robe - it's actually identical to her sister Emmeryn's outfit. Lissa's future son Owain also gets a dark yellow colored myrmidon/swordmaster outfit.
Both Miriel (first generation) and Brady (Maribelle's son) get unique-looking sage's robes (Miriel's is black with a thin gold collar, while Brady's is dark purple with the same Roman Numeral collar as Lissa's), and Brady also gets a black and purple war monk outfit.
Cordelia and her daughter Severa have red lining for their Pegasus knight and mercenary/hero outfits. Flavia's hero uniform also has red linings.
Nowi, Nah, and Tiki are green, red, and bright yellow-colored dragons, respectively.note A female Morgan, if any of these women are her mother, can also become a dragon, but will always have Nowi's coloring
Both Anna and Gangrel have red and yellow/black colored Trickster outfits, respectively.
Finally, Say'ri has a light purple swordmaster outfit.
The vast majority of enemies in Golden Sun have three recolors throughout the game. The few that don't generally have a Dummied Out third color. Even about half of the bosses are derived from this.
In Jade Cocoon 2, some Divine Beasts come in multiple elemental varieties. For example, Mau Divine Beasts come in Fire, Wind and Earth varieties, each with their own stats and attacks, but not Water because it is the opposite to the Mau family's main element, Fire.
The standard editions of the Kingdom Hearts games mostly avoid this (surprising for a Square Enix game), only using palette swaps to denote the elemental affinity of the mage-type Heartless; however, the Final Mix editions of both games use palette swaps in interesting ways. First of all, nearly all of the standard Mooks in the Final Mix games have had their colors changed from the original game's colors—for example, the first game's purple and pink Wyverns became blue and gold in the original Final Mix, and the second game's blue Hook Bats became red in Final Mix+. Some enemies, such as the black Shadows, remained the same in all editions, and though there was a rumor that the palette-swapped standard enemies had their stats tweaked, they really are the same enemies. The Final Mix editions of the game also included extra monsters; of these, many of them are palette swaps of standard enemies with slight changes in the mesh, high stats, and a host of annoying special abilities.
This isn't the case in 358/2 Days. Most of the bosses are larger palette swaps of average heartless you fight normally, with a few other minor aesthetic alterations. Also, some of the Keyblades are palette swaps of each other, and when you equip the Zero Gear, the Kingdom Key+ is just the Kingdom Key with higher stats. Though this could be justified considering this is a DS game and they focused on putting the good stuff in other areas. Which they did pretty well.
Also from Days: Xion is a palette swap of Roxas minus the dual-wielding.
The dream eaters in Kingdom Hearts 3D are perhaps the most notable examples of this in the series, with the friendly Spirits having bright colors, the Nightmares having dark colors, and the rare Nightmares using a blueish-white as their primary body color instead of whatever the normal versions used. The only differences they possess aside from color are the shapes of their eyes; the Nightmares all possess circular red eyes, whereas the Spirits have four different shapes per variety that change based on their disposition.
Kingdom of Paradise's field enemies consist merely of differently-colored versions of a few models (archer, swordsman, golem). The color of the uniform lets the player know which clan they're from.
All drell characters in Mass Effect 2 look exactly identical save for skin colour. Multiplayer characters in Mass Effect 3 are palette swaps of various Mooks and player's armor suits. This is also true for the case of the Earth DLC's N7 kits as only players who are very familiar with various armor sets are likely to recognize that: The Fury is Kasumi with a metal mask; The Destroyer's skin is based on the Terminus armor; The Demolisher has reskinned Cerberus Ajax armor; The Paladin has Inferno armor; The Shadow has a skin similar to a Phantom; and The Slayer is Kai Leng with an Alliance fighter pilot's helmet.
Mega Man Battle Network uses this a lot - while there are numerous viruses over the six games, each has three to six different palette swaps, e.g. Mettaur, Mettaur2, Mettaur3, and MettaurOmega, just to name one set. Third-level and Omega viruses often have slightly changed attacks, but for the most part, the only difference is increased HP, speed, and damage output.
The Omega versions of the bosses in the fourth game also receive a palette swap, perhaps to help indicate that they're on a completely different level from the previous versions strength wise.
The same is true of Mega Man Star Force. Met viruses, for example go yellow -> red -> blue, with their health, damage, and the speed at which their attacks move increasing; the later ones are also more likely to retreat into their helmets. Star Force 2 also has different colours of Mu wave soldier, denoting elemental alignment rather than power.
Monster Hunter uses Palette Swaps to differentiate standard wyverns from their upgrades. For example, a low level Rathalos is Red, a medium powered one dark blue, and a high level one silver.
MOTHER 1 did this, but had the decency to occasionally add subtle changes to their swapped sprites (a dog-collar on the wolf sprite to make a 'stray dog', rust marks on the robot sprite to make the 'scrapper'...)
EarthBound parodied this by giving the palette swaps goofy names.
The Persona games make use of this. All enemies in 3 and 4, even bosses, save for the plot related ones, are palette swaps of their base-type.
The various Phantasy Star games have used this. The first Phantasy Star had one notable (for an ancient 8-bit game) detail: the skeleton-type enemies had a different shield design for all three of their swaps.
While the series avoids doing this with their own Mons (with the possible exception of Plusle and Minun, who are palette swaps of each other on purpose), the anime likes to reuse trainer designs they've already done, including an audience for Contests.
Backlash ensued when in Gen V, the Kami trio turned out to mostly be this. (There are some minor differences in the tail, but essentially they are Palette Swaps of each other). It's alleviated a bit in Black and White 2, however, as the Kami trio are all given alternate "beast" forms that are very different from each other (being a bird, a dragon and a tiger, respectively)
Shining the Holy Ark was really bad with this, to the point where simliar looking enemies would reappear in the dungeon after the next. It was probably because they were all heavily animated (for the time) so the game couldn't physically have as many enemies.
Shining Wisdom is split into two areas, east and west. Most of the enemies in the east (the latter part of the game) are just the same enemies with a different colour scheme and new attacks.
The earlier Shin Megami Tensei games loved to do this. The most notorious example? The three seraphs' sprite when they are in your party is the same as the archangel's: the second demon of the "divine" clan.
Skies of Arcadia mostly averted this, save for a few types of enemies that reappear. However, it's played straight with the Looper enemies - as Arcadia has six colored moons, a different colored Looper is founds depending on what region you're innote They are:red Loopers in Nasr, green Loopers in Ixa'taka, blue Loopers in Yafutoma, purple Loopers in the Lands of Ice, yellow Loopers in Valua, and white/silver Loopers in the mostly empty region under the Silver Moon. There is also a far-reaching area in the world where you can find all six varieties of Looper, in addition to a giant orange Looper that you must fight with your ship. Finally, a Bonus Boss, Elcian, is a black Looper that is found in the Dark Rift.
Sword Of Vermilion was a heavy offender from the 16-bit era. All the common enemies came in six different colors (in order of ascending power: green, blue, red, black, silver, gold). Also, only the Final Boss was truly unique, all other bosses were palette swaps of four different models (dragon, giant, fire demon and necromancer).
Tales of Legendia is a big offender. The same twelve enemies appear constantly throughout the game, sometimes twice in the same dungeon, with only their palettes swapped out. This gets ridiculous within the first ten hours of the game, but in a seventy hour game, it begins to feel incredibly monotonous.
The World Ends with You does this with the Noise. There are sometimes cosmetic differences between the various versions of each Noise species, and the boss versions of a few of the more powerful versions often have tattoos all over their bodies in addition to more threatening characteristics (bigger horns/tusks), but overall most Noise are palette swaps of about fifteen or sixteen different species. Unlike all of the other bosses, who except for the two bat bosses and boss versions of normal Noise all have unique sprites, the Bonus Boss is a palette swap as well, of two of the bosses, one on each screen.
The 7th Saga has the infamously Genre SavvyBounty Hunter Pison, who, after begin defeated the first time, shows up unexpectedly later in the quest and proudly announces that he is now Red-Pison. Turns out to be Exactly What It Says on the Tin, and you immediately fight a stronger version of the original enemy, now palette-swapped to red. He even does this again even later on, becoming Metal-Pison and getting a gunmetal gray recolor.
In .hack//G.U., Atoli and Shino are palette swaps. Of course, this is easier to understand when you remember that this takes place in an MMORPG; that, and the fact that they look the same is a major plot point. Also, all the NPCs running around "The World" consist of palette swaps.
A number of characters from .hack//SIGN and the first PS2 game series are palette swaps of each other, including Bear and Orca, Mimiru and BlackRose, and Tsukasa and Elk. This is Played for Laughs in the .hack//Gift OVA, where one of the Blademasters (Bear and Orca's class) is killed in-game, and because dead characters are grayed out, nobody can tell which one of them it is.
Shoot Em Up
The different enemy factions in BLOODCRUSHER II are just reskins of the same basic enemies.
One of the final bosses in Darius Gaiden is a palette swap of the first boss, making for a nasty trick for any unprepared player.
Galaxian was the first game to have palette-swapped enemies where sprites were multi-colored. In fact, this is the oldest game to have multi-colored sprites.
Hardcore fans of the Gradius series were disappointed to discover that in Gradius V, the Player 2 ship was not Lord British (the red, single-nosed 2P ship of Life Force), but just a red-colored Vic Viper.
The Guardian Legend does this with bosses Fleepa, Optomon, Bombarder, and Clawbot, each of which recurs in different colors, and the last of which reuses the top half of the Bombarder sprite.
Raizing's "Bat" series of shmups does this differently. Pressing certain buttons or button combos not only changes the palette of player ships, but also gives them different abilities, such as enhanced speed, bomb, shot and option firepower, and in some cases, a smaller hitbox.
Yars Revenge does this quite oddly. The Quotile constantly palette swaps as part of its normal function, going through a rainbow of the colors that the 2600 could produce. When it turns red, it becomes a Swirl and tries to kill you. On later levels, if the normally red shield around the Quotile is blue, the Quotile will turn into Swirls when it turns blue and yellow as well. Of course, the original red Swirl is faster and usually trickier to avoid/kill.
In Descent and Descent II, some enemy robots would have textures that looked like textures found within the games' walls or floors. Although some were for camouflage, some 'bots had their textures changed to denote different behavior (such as dropping bombs, instead of firing laser or missiles or what-have-you).
Red Medium Hulks are three times tougher than Brown Medium Hulks, and use homing missiles, in barrages, nonetheless. Class 2 Platforms have a green Demonic Spider variation that shoots rapid-fire concussion missiles. Play In Descent II, the goddamned Red Hornets later have a more demonic green variant, the Spawns.
Harvest Moon Grand Bazaar was really lazy with this in comparison to the rest of the series. While the other games will use palette swaps for minor characters and other insignificant things (items, animals, etc.), a lot of the major townspeople in Grand Bazaar share sprites with at least one other villager. The two main character choices (a male and a female) are just swaps of each other. Claire shares the same sprite with Nellie, and Isaac with Wilbur; Cindy with Lauren (justified, because they're twins), along with every other young girl (including your daughter); Kevin with all other young boys (including your son); Ethel with Joan; and Raul with Diego and Enrique (they're all brothers). They at least get somewhat different Character Portraits, but because of this they wear really similar clothing in their artwork.
In Punch-Out!!, each of the boxers (except King Hippo) has a swapped counterpart with a different face:
The arcade version has Glass Joe and Kid Quick, Piston Hurricane and Pizza Pasta, and Bald Bull and Mr. Sandman.
The NES version has Glass Joe and Don Flamenco, Von Kaiser and Great Tiger, Bald Bull and Mr. Sandman (returning from the arcade game), Vodka Drunkenski / Soda Popinski and Super Macho Man (returning from the arcade sequel Super Punch-Out), and Piston Honda and Mike Tyson / Mr. Dream.
Super Punch Out for SNES has Gabby Jay and Bob Charlie, Bear Hugger and Mad Clown, Piston Hurricane and Aran Ryan, Bald Bull and Mr. Sandman, Dragon Chan and Heike Kagero, Masked Muscle and Super Macho Man, and the two Bruiser Brothers (sharing their own model). The only original palettes are Narcis Prince and Hoy Quarlow.
Averted in the Wii game, in which for the first time, all of the characters have distinct character models, although they still have similar appearances, indirectly referencing this trope.
Almost all of the non-plot-related enemies and characters in Disgaea have higher class ranks that are palette swaps of their base class, each with slightly better stats than the last.
Disgaea 3 introduces a service that allows one to change a unit's color to that of any of their other creatable ranks for a fee, and 4 expands on it by introducing unique colors that aren't used by any of a class' ranks, and extends the palette swapping privileges to unique characters.
Also in 3, various Palette swaps of Mao are important to the plot as "Inner Mao"s
All generic units, enemy and ally, in the Final Fantasy Tactics series are color swaps of each other so players can identify units from each other. Example, a Nu Mou Black Mage is generally clothed in blue while an enemy one has red clothing.
This makes things moderately confusing when you have to fight Blue Mages dressed in red and Red Mages dressed in blue.
In tactics A2 this becomes funny. The red king is dressed in blue, the blue king is dressed in red, the the black king is dressed in red, the green king is dressed in purple. not only that, they aren't master of their namesake magic, they use others more. So apparently magic types can get palette swapped as well.
The Fire Emblem series plays this in several different ways:
There is usually just one or two (if both genders are possible) character model per class; everyone in a particular class is a palette swap of that model. Generic units are coloured by affiliation, while playable, boss and other important characters have their own unique colour scheme. Some characters have their own individual class (e.g. Lord) and thus look unique. Radiant Dawn alleviates this to some extent by giving every player and important character a unique skin to their model which reflects their actual appearance, but the model's animations do not change at all. That is why the fans clamor for the official character art—these portraits tend to add a touch of personalization that the in-game models often do not portray.
Several exceptions exist to this tendency, particularly in the GBA era. The Sacred Stones introduced three apprentice classes; there is only one character each that as such looks rather unique... until he/she promotes into a proper class. Blazing Sword's Hawkeye - comparatively not that important a character - has his own completely unique Berserker sprite which differs significantly from the normal in its movement, whereas all other Berserkers use the generic sprite. Weird.
Fire Emblem Awakening has an odd variant for the second-generation playable characters: palette swapping their hair colors depending who their parents are.
Heroes of Might and Magic suffers from a bad case of palette swapping when units upgrade. Granted, some bells and whistles are usually added, but it's painfully obvious the models were built from the same sprite.
This is possibly a Justified Trope since upgraded units are supposedly the same units as pre-upgrade.
Surprisingly for a game of its complexity, Jagged Alliance 2 has this. All enemies, mercs and militia are basically the same 3 models (Big Male, Regular Male, and Female) with a different palette for each. Mercs have the most diversity, as each has a different clothing color combination, and of course there are all sorts of combinations for hair color and skin color for everyone in the game.
Luminous Arc and its sequel are horrible about this. There are probably less than ten different monster sprites that are recolored to make all the generic enemies you face.
The economic edutainment game M.U.L.E. does this with the players' characters if any of them are the same species, but since they only share the screen during auctions, it's not really a problem.
Rome: Total War loves this tropes, especially in Barbarian Invasion, to the point that the Lombardi and Burgundi factions are otherwise identical Palette Swaps of each over in every way possibly. The same holds true for Sarmatian and Roxolani units, being colourcoded yellow and blue, respectively.
The Koubu mecha in the first Sakura Taisen games are identical aside from color. The second game added another set of sprites for the two characters with European designed mecha. Once the games entered 3D with the third game, each characters mecha became more individualized with unique emblems, animations, and weapon models.
Shining Force III does a pretty good job of subverting this, until around half way when you notice the earliest monsters reappearing but with a different colour. The humble bat, one of the earliest enemies, reappears in Chapter 4 as the Vampire Bat which is bright red.
Wide Open Sandbox
Prototype has both lighter-colored USMC and darker-colored Blackwatch palettes of military vehicles, the ones you can actually hijack. Blackwatch ground vehicles are tougher to kill while their aircraft carry more ammunition(and are also slightly tougher), than their Marine counterparts. They can also be easily identified with their respective logos too.
Also the civilian populace, where any given civilian model has a few color themes affecting attire and skin.
In Saints Row: The Third, you can unlock new skins for your gang members (like hookers, cops, mascots, National Guard soldiers, and even rival gang members) by completing story missions and minigames. If you actually apply these skins to your gang, it quickly becomes obvious that they are simply palette swapped versions of the originals, right down to the ones modeled on rival gangsters continuing to make disparaging remarks about the Saints during battle.
The majority of the Space Pirate fighters in X3: Reunion and later games are standard faction fighters (mostly Argon and Teladi), but with sweet Nose Art. They retain the turrets and most of the stats of the base ship, though they often can carry a more varied loadout, at the cost of being inferior to the standard ship. X3: Terran Conflict introduced several Ace Custom pirate ships with unique models, and proper Pirate capital ships.
Non-video game examples:
Every year people get ads in their newspapers showing collectibles for the big local pro or college sports team. Ceramic villages with the team logo on it, Santa wearing the jersey, etc. What you don't really see until you go online to their website is almost every city got the same ad for the same village and often the only thing different in the picture is the team logo and colors.
Sometimes, the difference in color is used to denote a variant of a different level, attribute type, or associated with different elements/powers. For example, Otamamon's has water powers and is of the Virus attribute, while Otamamon Red is associated with fire and is of the Data attribute. Both are of the Child level. On the other hand, sometimes there are less reasonable instances: there's Monochromon, an Adult, and Vermillimon, a red Monochromon of the Perfect level. There are many more examples.
Digimon World is horrible about doing this to differentiate random enemy Digimon from recruitable ones. You can recruitBetamon and Drimogemon (frog and drill-nosed mole, basically). You fightModokiBetamon and NiseDrimogemon. (Modoki means 'seems like' or 'looks like;' Nise means 'false.') The only difference at all between them is that ModokiBetamon is a slightly different shade of green and NiseDrimogemon has a mustache instead of whiskers.
Not as bad as Gottsumon, a Child-level golem Digimon who has two palette swaps, Icemon and Insekimon. At least Icemon (Adult-level) is clearly white as opposed to Gottsumon's grey so you can easily tell them apart, but Insekimon is distinguished from Gottsumon and Icemon solely by being a slightly lighter shade of grey with a green tinge, and what really takes the cake is that he is a Perfect. You heard correctly, a Perfect is a palette swap of a Child. This was lampshaded neatly in Digimon Savers - when Gottsumon evolves to Insekimon, Yoshino comments that all that seems to have changed is his colour.
Gururumon has to be Bandai poking fun at themselves over this practice. The difference between Garurumon and Gururumon is that Gururumon's blue stripes are slightly more purplish in hue; I dare you to tell them apart if you don't have their pictures/trading cards side by side. Many are the fans who thought that "Gururumon" was just a typo.
Vegimon has two palette swaps: Zassoumon and RedVegimon. RedVegimon, at least, has the decency to differ in design somewhat insofar as having large clubs at the end of its tentacles instead, but otherwise it just looks like a Vegimon that is blue.
The third kind is random recolourings which serve no purpose at all, are given little to no context, are not differentiated from the main Digimon at all, and seem to be there for the hell of it. Digimon World 3 is a massive offender in this regard. The entire Amaterasu Server (before you free it) is a Dark World-themed palette swap of the Asuka Server, and most of the Digimon in it are palette swaps of the ones from Asuka.
The Tendou sisters in Il Sole penetra le Illusioni are triplets, which sort of justifies them often being literally copy-pasted and colour-tweaked. Also, Etia and Ariel's outfits are identical except for colour and the pattern on their circle-things.
The "Rose Bride dress" of Revolutionary Girl Utena: The original dress is red and worn by Anthy during the duels. In the first ending sequence and in episode 38, Utena wears a light pink version of the dress, and in the third story arc, Kozue and Shiori gain dresses that match their hair colors (indigo and purple, respectively).
During Yu-Gi-Oh!'s DOMA Arc, Jonouchi / Joey adds the Blue Flame Swordsman to his arsenal. This is, unsurprisingly, Exactly What It Says on the Tin—a blue Palette Swap of his already existing card, Flame Swordsman, with the exact same stat (ATK: 1800, DEF: 1600, Level: 5). On the plus side it does have a useful ability that the original card does not possess—when it's sent to the Graveyard it allows Joey to summon a regular Flame Swordsman to take its place.
Kisara is basically Serenity with white hair and pale skin.
The Hobgoblin is effectively a palette swap of the Green Goblin.
In Ultimate Comics: Avengers, Gregory Stark is introduced as Tony's twin brother. He has blonde hair and wears white suits.
A particularly lazy example; as seen on the author's YouTube video on the characters, as the cast consist of just recolours of Twilight Sparkle, Rainbow Dash, Fluttershy and Scootaloo. Made even more obvious by the fact that; with the exception of Lightning Dawn, the author never actually bothered to recolour their eyes. Rhymey isn't even a recolour just Fluttershy with a horn, clothing, yellow tail, mane and different hairstyle.
Starla Shine is according to recent videos just a Rarity clone, but not as shallow as the original. He has tried to cover this up by... slightly darkening Starla's coat, which he feels "ruins the design".
That's just the tip of the iceberg. There's also Mattboo Sux, Sidney, Casy, "Evil Pac-man 64 clone", etc.
That may be explained by the fact that the original character designs were made in MS paint.
Many, many, many O Cs have been created this way. Their creators merely swap out the colors of their favorite canon characters and replace them with new color schemes. The fact that there are literally thousands of base/lineart makers on sites like DeviantArt only aids the widespread trend. Fandoms of My Little Pony, The Lion King, Sonic the Hedgehog, Pokémon and many other Sailor Earth shows and movies are particularly prone to this.
The movie Grandma's Boy, which is about video game designers, references this tendency when one tester recommends differentiating between two types of enemies by changing the colors of one of them.
The Starfleet uniforms seen in Star Trek: First Contact are an inversion of the uniforms worn on Star Trek: Deep Space Nine and Star Trek: Voyager, being predominantly black with grey shoulders and colored shirts, unlike DS9/Voyager's uniforms which had gray shirts and colored shoulders. The DS9 crew would shortly switch to these uniforms for the rest of the series, whereas Voyager's crew, stuck in the Delta Quadrant, stuck with their uniforms till the end, though subsequent episodes involving the Federation at home featured these uniforms.
Wreck-It Ralph used this for several of the background Sugar Rush racers. Both meta and in-game. Of course, when you have a racing game featuring Loads and Loads of Characters, and especially one from 1997, this is to be expected.
"At the beginning of the film, Charles is medicating, and very possibly on hallucinogens, so we had that come through in his shirt. As he pulls himself together, he wears a nice blue oxford like all good, put-together men—a progression from that psychedelic Cat Stevens-wear."
In Denji Sentai Megaranger, the suits, which often have some sort of variety per season, are rather homogenous this time around save color. Perhaps a moment of Fridge Brilliance, since this season was about video games, particularly ones made in the mid-90s.
The same thing happens quite frequently in Dinosaurs. Every single puppet not used for a protagonist was used as countless different characters, made male or female simply by changing the clothes.
The newer series of Kamen Rider have tended to reuse the same rubber suits for their Monster of the Week, with the differences ranging from a complete repaint to a differently coloured scarf. Sometimes this is given a lampshade, as in Kamen Rider Agito where monsters embody members of certain animal genera (and thus Agito fights three recolored jaguar monsters in the first two episodes). Considering that the cost of creating one of these expensive monster costumes from scratch greatly outweighs the cost of a simple repaint, it's more due to budget constraints rather than a lack of creativity. Some Kamen Riders also fall prey to the budget-saving repaint: most of the movie-only Riders, Evil Twin Ryuga from Kamen Rider Ryuki, the Super Prototype Hopper Riders and Evil Twin Dark Kabuto from Kamen Rider Kabuto and Zeronos' Deadly Upgrade Zero Form from Kamen Rider Den-O.
In the Psych episode "We'd like to thank the academy", Shawn shoots two civilian cardboard cutouts in a training exercise. His justifications:
"The first woman with the groceries was exiting a library that doesn't allow snacks. I know this because we've tried on several occasions. And the second woman was simply a replica of the first woman, but they painted her face brown, which is both offensive and suspicious."
The MAD Magazine comic Spy vs. Spy features the titular black and white spies, palette swaps of one another.
A number of Muppets are actually the same puppet with different clothes, hair, and other accessories. The Creature Shop calls them "Anything Muppets." Sesame Street fans reading this will probably not be surprised to learn that the characters Prairie Dawn and Betty Lou, for example, are the same puppet, not to mention Zoe and Rosita.
Miniatures wargames will often have this. The players will actually play the same army by the same rules, but represent in universe alignments by paint scheme. For example, one player may represent the WWII 10th Mountain Division and another may represent a US Ranger Battalion by using the same miniatures and rule set, but simply paint the 10th in snow and the Rangers in drab greens. This is especially prevalent in Warhammer and Warhammer 40,000 where many in universe armies might follow the same rule set.
In the case of Warhammer and Warhammer 40,000 a number of factions started out life as simple palette swaps, but have developed over the years to get their own models and/or rules. The Space Marine chapters are a good example - originally Blood Angels, Dark Angels, Ultramarines and Space Wolves were just red, dark green, blue and grey versions of the same thing, but now they have their own distinct stylings and rules. Other factions, such as Eldar Craftworlds and Ork Clans, are still just different colour schemes, though each can be characterised somewhat by choice of units taken as well as the livery.
G.I. Joe has several 'covered head to toe' enemy characters. Each meant to be a different mook an identical uniform. Swaps come as ideas do. The 'Python Patrol' was, storywise, a way to make characters invisible to sensor equipment. The heroes had, for example, 'Tiger Force', which swapped the usual uniform colors with yellow, brown and red. Nameless Joe Greenshirts (think 'redshirts') got this, though their heads were clearly seen. Some were logical (light skin and a tanned one could mean a sibling was in the sun) but others were different races, same facial features.
Hot Wheels at least acknowledges its recolors for different model years are the same cars, but one can pinpoint which model year a certain car comes from by the paint job.
Nearly every LEGO minifigure ever, if for fairly understandable reasons. It's only within the past few years that they've started implementing unique body, limb and head designs for non-human characters.
In BIONICLE, the act of palette swapping represented a very disliked trend throughout the line's early run, commonly known as "clone sets". The most infamous case is that of the Bohrok and Bohrok-Kal lines: 12 sets that, beyond their weapons (and usually their collectibles), are exactly the same model, just in different colors. The same could be said for most of the Matoran sets, which only differed in their colors and/or mask designs. Yet narrowly avoided by most of the original Rahi two-packs which had two almost identical models, but each had at least one tiny detail that differentiated it from its partner (the exception being the Nui-Jaga scorpions). Outside of the toys, story material also had its share of these, but not many were truly canon. The green Vortixx from the comic Shadow Play was colored that way so that the readers could tell him apart from the black Roodaka. On the other hand, Tuma's green colored Rock Steed from Rise and Fall of the Skrall is canon. As a result, most background extras in the animated films were just recolors of the same handful of models. Even the Vahki soldiers used the same model, despite that their toys at least came with unique weapons. And in the third movie, the Muaka tiger was a mere palette swap of the ash bear from the first, with a slightly retooled head — it looked nothing like the actual Muaka toy, so they explained that it was really a mutant.
At the beginning, Hero Factory somewhat dipped back into the practice for its Heroes (the villains still averted this). This was somewhat justified, however, as they were built in a factory as variations of the same basic design rather than individual and unique life-forms. The first wave Heroes were recognizeable solely by their different helmets, weapons torso armour designs (the three rookies had the same one, however). The 2.0 and 3.0 waves, thanks to the new building style, added subtle differences that made each Hero unique: limbs length, shoulder width, armour size and orientation, colour schemes. By the Breakout arc, though Heroes are still all built off the largely same basic frame, Hero designs are even more varied in height, designs, colour schemes, armour and other elements.
Not only do the line of My Little Pony: Friendship Is Magic figurines resemble more toward pre-G4 versions, but various background characters (sometimes not even existing in the series) are palette swaps of the main characters, if their packaging graphic is anything to go by. For instance, look up Dewdrop Dazzlenote of Twilight Sparkle, Feathermaynote of Rainbow Dash, Flitterheartnote of Fluttershy on her brushable packaging and collector's card, but her blind bag figure is based on Rainbow Dash, Lulu Lucknote of Rarity, Plumsweetnote of Pinkie Pie, Snowcatchernote of Rarity also, Diamond Rosenote of Fluttershy again, and Twinkleshinenote of Rarity yet again, if you're already familiar with the main G4 cast. Some other examples show attempt to differentiate however, such as "Cupcake" being a wingless version of Fluttershy, or "Sunny Daze" being a non-unicorn Sweetie Belle, or even "Minty" as an Applejack mold sans the hat.
The "blind bag" minifigures even went so far as to have Fluttershy - one of the Mane Six! - as a Pallete Swap of Rainbow Dash. (Which is somewhat amusing after the events of the third season episode "Magic Duel"...) She finally got her own unique mold in a set released in mid-2013. Several other characters who've appeared on the show, though, are still recolors at the blindbag scale, such as Cheerileenote of Pinkie Pie, Trixie Lulamoonnote of Rarity in wave 4, then of Twilight Sparkle in later issues, Lyra Heartstringsnote of Twilight in the blind bags, but Rarity in the Groovin' Hooves◊ set, Bon Bon(Sweetie Drops)note of Applejack, Daisy(Flower Wishes)note Pinkie Pie again, Blossomforthnote Rainbow Dash again, and Peachy Pienote also of Pinkie Pie, ironically.
Nerf blasters are often released in recolored versions as store exclusives, notably the Sonic Series from Toys R Us, the Clear Series from Target, and the legendary Red Strike series from Walmart, which was only for sale for one Black Friday and is now one of the most sought after and expensive repaints ever in Nerf history.
Transformers being what it is frequently redecos (puts different colors and painted designs on an old mold) and/or retools (puts new parts on old models) the same model several times to get better return on their toys. This can vary from a new paint scheme on a character to making a completely different character. Starscream, in particular, shares most of his body with his fellow Seekers, Thundercracker, Skywarp, Sunstorm, and Acid Storm. Move some things around (retool) and you get the 'coneheads,' Thrust, Dirge, and Ramjet. Even Optimus Prime gets reused as a different guy from time to time. Original Ultra Magnus? Totally a Prime repaint with a different trailer◊. Magnus' robot mode is actually the toy's Super Mode - the toy's normal robot mode is never shown to avoid confusion. And then, of course, there are all the 'evil' repaints, such as Scourge (repaint of Generation 2 Laser Prime toy) and the various incarnations of Nemesis Prime (Scourge color scheme added to other Optimuses... Optimi?) There's even a Nemesis Breaker, an Evil Twin of Leobreaker from Transformers Cybertron.
Transformers Cybertron interestingly avoids this, for the most part (okay, not in the toyline), with Thundercracker having a standard Seeker body... but Starscream himself is a completely different design, with only the head looking particularly Starscreamy. (It's actually based on Screamer's pre-Earth design from the War Within comics.) The exception is Galvatron. After upgrading to Galvatron, visually, Megatron is Palette Swapped to G1 Megatron's colors. Major Homage, bordering on non-sexual fanservice.
Actually lampshaded and justified in Transformers Prime, where Skyquake and Dreadwing are explained as twins with two halves of the same spark, explaining why they look essentially the same, just with different colors. Fowler even lampshades, multiple times, how he essentially gave the same alt-mode to two different robots (he was piloting the same jet when facing each of the brothers).
Also justified in Transformers Animated, there they were explained as having the same "body type" in-fiction. Oddly, though, only a handful of toys actually got recolored, namely Starscream as his clones and a couple of Bot Con exclusives. More recolors came out in Japan or were cancelled before release.
This has been done so often in both the official toyline and the shows, that it's considered a fairly acceptable method of inventing an Original Character (that one plans to create art of).
Hasbro also has a habit of doing this with their superhero properties. For instance, their Avengers AssembleHawkeye figure is just a Hawkeye from their earlier Avengers movie line with some purple coloring thrown in, and their Falcon figure from Captain America: The Winter Soldier is an Avengers Assemble Falcon toy with a new head, a black costume, and the wings changed from energy constructs to mechanical designs.
In Aventure Dennis the protagonist fights Shadow Dennis a palette swapped version of himself.
The world of Adventurers! apparently suffers from a severe case of this. The characters get to fight monsters like dark blue spectres and navy blue spectres, each requiring different tactics to defeat. It was also lampshaded in a discussion between the Big Bad and his minion, where the Big Bad complains he has no time because he has to create new monsters to send after the protagonists, and the minion points out he usually just takes an existing monster and puts 'Ice' in front of it's name.
In later seasons, when the current game in the series allowed for customized pieces of armor, this cleared up a bit.
Being one of the web's most potent Fountain of Expies characters, there are a massive number of recolored Sonic the Hedgehog lookalikes on sites like deviantART. The least modified are simply Sonic with a new color scheme or some clothes on.
On user-created-adoptable site Squiby it's common for users to take a single format for a creature and use creative colorfills to make multiple versions. Some popular lines that use this formula include Mites,Tencats,Shika and Coons.
Downplayed in Aelan mythology from Ustal Naror islands: colour is not the only difference, but is most visible in case of, for example, ancients and moderns
Rapunzel's wedding dress in Tangled Ever After is actually her homecoming celebration dress colored white instead of pink.
Lois' sister, Carol, is basically another Lois with different hair and clothes. They sport the same exact face and body shape.
In the Futurama episode "The Farnsworth Parabox" the crew of Planet Express goes to a Parallel Universe where they meet palette-swapped versions of themselves (Fry has black hair, Bender is gold-plated instead of gray), otherwise nearly identical in personality.
In Gargoyles, Owen and Vogel. They say nobody's ever said they look alike. Turns out it's because Puck based his Owen identity on Vogel, the trickster enjoying the irony of playing The Comically Serious.
One somewhat bizarre non-Video Game example are Wile E. Coyote and Ralph Wolf. They were basically identical, except Ralph had a red nose and Wile E had a black one, and they lived in different areas.
In The Mr. Men Show, Mr. Bounce looks like a yellow Mr. Tickle with a pink hat instead of a blue one.
A lot of background ponies on My Little Pony: Friendship Is Magicare palette-swapped multiple times to make new background ponies. Sometimes even major characters themselves are palette-swapped to make background ponies.
The white nurse pony from "Applebuck Season" has a palette swap background pony from the same scene.
The two spa owners from "Green Isn't Your Color" have the same character design but with inverted color schemes.
The band that performed on stage in the episode "Luna Eclipsed" are actually palette swaps of the band from "The Best Night Ever" but are wearing scarecrow costumes. Fiddly Faddle, the Octavia palette swap, also appears in "Apple Family Reunion".
The multicolored parasprite swarm all share the same character design.
The various versions of Applejack and Rarity that Twilight makes during the titular "Magic Duel" look like pallete swaps of fillies and various other members of the apple family. This is because they really are pallete swaps, as Twilight is not strong enough to actually cast those spells, so the Apple Family and Sweetie Belle disguised themselves with paint and hair dyes instead. Likewise, Fluttershy is painted in Rainbow Dash's colors for the duplication illusion.
Sabrina Alberghetti's OC, Wild Fire, has two palette swaps, unofficially named "Wild Flower" and "Rainbow Drop".
Fairly common in South Park for background classmates at the boys' school, or for adults in other crowd scenes. Although the animators have put together more distinct character models for extras in recent seasons, palette swaps can still occur when they don't feel up to making even more new ones.
Many extras on SpongeBob SquarePants are Palette Swaps of each other. For example, the My Leg and Deaugh fishes.
The villain in the Teen Titans: Trouble in Tokyo movie summoned several Palette Swapped copies of previously created villains for the final battle.
Totally Spies! has a Shout-Out example with the girls' predecessors, Pam, Alice, and Crimson. The women look almost exactly like Hitomi, Ai, and Rui from Cats Eye, just with different hair and eye colors.
In the Donkey Kong Country CGI cartoon, the character model for Eddie the Mean Old Yeti is the same as Donkey Kong's, but with white fur and a cap instead of a necktie.
Any product that is mass produced can also be made with different colors. Cars are a big example of this.
Nintendo is very fond of making their consoles and accessories in different colors. The Nintendo 64 had controllers of various colors, ranging from red, blue, green, purple, etc. The console itself would also be produced in colors beyond black late in its life. When the Gamecube was launched, it came in either black or purple, along with its controllers. Later on, there would be a silver/platinum version and for a short time, there was orange, but that color was used only for the controller. The Wii initially released only in white, but it was also produced in black years later and there were controllers in black as well, along with pink, blue, and a limited edition of gold. The Wii-U (so far) only comes in either black or white.
Badge engineering. A car company takes one of their cars, swaps out the badges, then maybe changes the bodywork slightly before selling in one of their subsidiaries. General Motors is/was infamous for this, famously selling seven versions of effective the same car in the 1980s, all in the same market. The modern Volkswagen group likewise does the same, though they usually make more significant changes between brands.
