[[caption-width-right:256:Player 1 is blue, and Player 2 is red. [[Film/TheCourtJester Get it? Got it. Good.]]]]

Video game sprites or polygon models of different colors to tell otherwise identical {{Player Character}}s apart. This was especially prevalent in games up to [[TheEighties the mid-1980s]], where [[UsefulNotes/ReadOnlyMemory ROM size]] meant that even different sprites for them would take up too much space. In later years, storage capacity has grown bigger, allowing game designers to give each player character a different design, but this trope lives on as a way for players to tell each other apart when they are both [[MirrorMatch playing as the same character]].

In early days, certain players were forcibly assigned certain character colors with no way to choose a different color (ex: P1 blue, P2 red, P3 green, P4 yellow); this was most useful in arcades, where the preassigned colors were often painted onto the controls and/or the surrounding area of the cabinet. Nowadays, games will often allow players to choose colors.

This trope can apply whether the multiplayer is cooperative or competitive. It can also apply to a MirrorMatch with a computer-controlled opponent as long as it is using the same character as the player.

In two-player games, you typically see Red and Blue; four-player games almost always add Yellow and Green. Red and Blue have historically been used, such as the red and blue corners in boxing, whereas the other two are included for ChromaticArrangement.

[=SRPGs=] often do this with the generic classes.

Also, there can be some minor differences, as long as the color is the primary way to tell them apart.

[[folder:Action-Adventure Games]]
* ''VideoGame/TheLegendOfZeldaFourSwords'' and ''VideoGame/TheLegendOfZeldaFourSwordsAdventures'' has Link shattered into four people by the Four Sword. His clothes are green, red, blue, and violet.
* ''VideoGame/CrashOfTheTitans'' and ''VideoGame/CrashMindOverMutant'' did this with the introduction of Carbon Crash, a white and green recolor of Crash. However, Carbon Crash is often deployed only when Coco can't be there plot-wise.

[[folder:Beat 'em Ups]]
* The arcade version of ''VideoGame/BadDudes'' had two main characters whose only differences were the colors of their parachute pants (white for Player 1 and green for Player 2).
** In the game's SpiritualSuccessor, ''VideoGame/CrudeBuster'' (aka ''Two Crude Dudes''), Player 1 wears yellow and has a faux-hawk style, while Player 2 wears green and has a bald mohawk.
* ''VideoGame/CastleCrashers'', though, going by the [=FAQs=], there is some debate over whether one of them is the Yellow Knight or Orange Knight. In addition, there are several unlockable enemy characters.
* ''VideoGame/DoubleDragon'' - In most games in the series, Billy (Player 1) wears blue and Jimmy (Player 2) wears red.
** The only exception is the arcade version of ''VideoGame/DoubleDragonII'', where Billy and Jimmy wore black and white respectively. The NES version brought them back to their original colors.
** The arcade version of ''Double Dragon 3'' allowed up to three players simultaneously, depending on the cabinet, in which Player 3 controls a yellow-clad Lee brother exclusive to this game named Sonny. There are other playable characters in the game (selectable from the get-go in the Japanese version, but available only as purchasable extras in the export versions), but rather than being individual characters, the additional characters are grouped as teams of siblings (Urquidez, Chin and Oyama), essentially an excuse to allow all three players to control the same character type, but with a different name tag and palette.
** In ''Super Double Dragon'' and ''Double Dragon Advance'', Billy and Jimmy actually have different hair styles for their sprites. Instead of the regent style they used in the arcade and NES games, Billy has straight brown hair, while Jimmy has a blond flap-top style.
* ''VideoGame/DynamiteDux'': Player 1 is the blue duck Bin, and Player 2 is the red duck Pin.
* Most games that copied the ''VideoGame/FinalFight'' template (usually 3 playable characters) followed this color scheme: [[JackOfAllStats blue]], [[FragileSpeedster red]], and [[MightyGlacier green]] (yellow for ''VideoGame/StreetsOfRage 1'').
* ''VideoGame/GoldenAxe'' featured [[FragileSpeedster Tyris Flare]] (red; the best magic, the best speed, but weak), [[JackOfAllStats Ax-Battler]] (blue; average magic, average attack, and average speed), and [[MightyGlacier Gilius Thunderhead]] (green; the worst magic, the worst speed, but has the best range with his axe).
* ''VideoGame/NinjaGaiden'' (arcade version) has Player 1 as a blue ninja and Player 2 as a red ninja. While neither character are actually identified in the game, Ryu Hayabusa (the main character in the NES version) wears a blue ninja outfit, while his father Ken wears a similar red outfit, matching the colors of the two player characters (leading some fans to [[FanWank speculate]] that the events depicted in the arcade version is a mission that Ryu and Ken Hayabusa went through before the events of the NES series).
* In ''VideoGame/RoboArmy'', Maxima (Player 1) wears red, while Rocky (Player 2) wears blue. However, the two characters are also {{head swap}}s, with Maxima having a human head with beret, whereas Rocky is completely robotic.
* ''VideoGame/ViolentStorm'' inverted it compared to most brawlers that followed the ''Final Fight'' template. Kyle wears green and is the [[FragileSpeedster weakest but fastest]]. Boris wears red and is the [[MightyGlacier strongest but also the slowest]], although not as slow compared to other mighty glaciers in brawlers. Wade wears blue and is [[JackOfAllStats average]] between the other two player characters.
* The ''Franchise/{{Superman}}'' UsefulNotes/ArcadeGame by Creator/{{Taito}} allowed a second player to play a Superman colored red and gray instead of blue and red.

[[folder:Driving Games]]
* ''VideoGame/DaytonaUSA'' gives each player their own car color, even in a round consisting of as many as 8 players. The colors are as follows -- 1P: red; 2P: blue; 3P: yellow; 4P: green; 5P: black; 6P: pink; 7P: cyan; 8P: orange.
* ''VideoGame/KirbyAirRide'', with additional colors as some of the unlockable rewards.
* ''VideoGame/MicroMachines'', the first two, would have this as their way of telling players apart, Player 1 being red, Player 2 being blue, Player 3 being green, and Player 4 being yellow.
* In ''Super Sprint'', the first player controls a blue car, the second player controls a red car, and the third player controls a yellow car. The AI-controlled drone cars are always gray.
* In ''Super Off Road'', player one controls a red truck (or optional dune buggy if they play the Track Pak version), player two controls a yellow truck, and player three controls a blue truck. The AI-controlled truck of "Ironman" Ivan Stewart (or "Lightning" Kevin Lydy in current re-releases) is white, though it appears gray due to graphical limitations. The NES version had a green truck in place of the white truck if four human players compete.

[[folder:Fighting Games]]
* ''VideoGame/UrbanChampion'' involves two almost identical boys beating each other up, differing only in clothing and hair colors.
* Every ''Franchise/StreetFighter'' installment since ''Champion Edition'' allowed both players to use the same character by distinguishing one player with an alternate color scheme. ''Super Street Fighter II'', the fourth ''VideoGame/StreetFighterII'' game, actually has eight palettes for each character, allowing all eight players in the Tournament Battle mode to use the same character. ''VideoGame/StreetFighterIV'' retained the tradition of palette swapped costumes, despite the switch from pixel art to polygonal models and the introduction of alternate costumes.
* ''VideoGame/DissidiaFinalFantasy'', the interesting part is that the alt colors make sense if you've played the other FF games or are otherwise a ''Franchise/FinalFantasy'' nerd--some of the alts are based on original concept art of the character that didn't make the final cut for the original game ([[VideoGame/FinalFantasyIV Cecil]], [[VideoGame/FinalFantasyII Firion, The Emperor]]), some are versions of the character as they appeared in their actual game, their default Dissidia design having changed that (Golbez, [[VideoGame/FinalFantasyX Tidus]], [[VideoGame/FinalFantasyVI Terra]]), and others make references more complicated than that (''VideoGame/FinalFantasyIII'' was originally a game of four {{AFGNCAAP}} [[HeroicMime Heroic Mimes]], while the remake did away with that and gave the characters all personalities, back stories, unique appearances, and [[CanonName names]]; Dissidia references this by basing the FFIII representative on the Onion Knight of the original game, while having his alt look like Luneth, the "hero" of the remake). And yet others are outfits the characters actually wore ([[VideoGame/FinalFantasyVII Cloud's]] [[Anime/FinalFantasyVIIAdventChildren AC]] outfit or [[VideoGame/FinalFantasyVIII Squall's]] Seed Uniform). And others are a referance to ''other'' characters (Ultimecia and Jecht).
* ''Franchise/MortalKombat'' used mainly shading variations (likely since Sub Zero, Scorpion, Reptile, Ermac, Human Smoke, Rain, Noob Saibot, and Chameleon were already {{palette swap}}s at various points).
** Also, the women, Mileena, Kitana, Jade, and the often forgotten Khameleon.
** As well as Cyrax, Robot Smoke, and Sektor.
* ''VideoGame/SuperSmashBros'' uses alternate costumes of characters marked red, green, or blue when playing team multiplayer. When the same character is on the same team, they're differentiated by being a slightly different shade from the other players. Free For All battles also had alternate palettes for each character, which can be selected from the menu.
** The fourth generation games for Nintendo 3DS and Wii U changed the presentation for team battles so that teams are indicated by color-coded outlines instead, allowing the freedom of giving players the character palette of their choice. A yellow team is also present for the Wii U version's eight-player mode.
** Also, in Free For Alls and Single Player mode, you can tell which controller port you're using based on the color of your shield/stock/icon/KO explosion; P1 (Red), P2 (Blue), P3 (Yellow), P4 (Green). Computer players are given gray.
*** As of ''Super Smash Bros. for Wii U'', an eight-player mode was introduced, so there are four additional colors: P5 (Orange), P6 (Cyan), P7 (Purple), P8 (Dark gray).
* ''VideoGame/TeenageMutantNinjaTurtlesSmashUp'' uses colored 'auras' to separate players, much like Super Smash Bros. in that they are required for team matches. In free for all matches, the aura colors can be decided by the player out of a standard 256 color pallet. While alternate models exist, this is the main way to separate fighters.

[[folder:First-Person Shooter]]
* The multiplayer for ''VideoGame/MetroidPrime 2'' involves multicolored Samuses (Samii?) fighting each other.
* ''VideoGame/TeamFortress2''. Lampshaded in that their companies are [[FunWithAcronyms abbreviated to RED and BLU]].
** It's lampshaded even further since the founders of said companies are named Redmond and Blutarch, respectively.
*** And after the Mann Vs. Machine update, RED and BLU have a common enemy called Gray Mann (whose "team", ironically, [[AvertedTrope isn't this]]--they're robotic doubles of the actual characters, as the "Vs. Machine" part of the update title implies).
* ''Franchise/{{Halo}}'': {{Palette Swap}}s were the only way of distinguishing players in the original ''VideoGame/HaloCombatEvolved'', with ''VideoGame/{{Halo 2}}'' offering a (rarely used) Elite player model. It wasn't until ''VideoGame/{{Halo 3}}'' that we finally got [[AndYourRewardIsClothes unlockable armor customizations]].
** Averted in co-op play in ''VideoGame/{{Halo 3}}'', ''[[VideoGame/{{Halo 4}} Spartan Ops]]'', and ''VideoGame/Halo5Guardians''. In ''3'', Player 1 is the Chief, Player 2 is the Arbiter, and the other two are unique Elites. In ''Spartan Ops'', each player uses their customized multiplayer model. In ''5'', each player is a different member of Fireteam Osiris / Blue Team.
** FanRemake ''VideoGame/HaloZero'' uses this too.
* ''Franchise/{{Halo}}''[='s=] predecessor, ''VideoGame/{{Marathon}}'', also had human players all look the same, but player sprites were split in two (primarily in order to avert FightInTheNude) so that the color of one's shirt and pants could be set separately, to denote both the individual player and the player's team.
* ''VideoGame/{{Quake}}'' (or at least [=QuakeWorld=]) also let players recolor the top and bottom halves of their models based on personal preference or team affiliation, and sometimes mods used this as well. The original [=QuakeWorld=] ''Team Fortress'' used pants color to assign people to the RED and BLU teams.
* The first ''VideoGame/{{Doom}}'' game's multiplayer had each player a different color. One of the colors was brown, and this mixed with the oldschool graphics and brown colored enemies caused problems.
** ''VideoGame/{{Heretic}}'' made the players red, yellow, green, and blue, averting the problem with ''Doom''.
** ''VideoGame/DukeNukem3D'', ''VideoGame/{{Blood}}'', and other first person games at the time followed suit.
* ''VideoGame/ProjectBlackout'' has a red team and a blue team (although the "red" team is sort of a misnomer--they actually wear camo).
* ''VideoGame/MondayNightCombat'' uses orange and blue for its two teams.
* ''VideoGame/BioShock2'''s multiplayer depicts friendly hacked machines with blue lights, and enemy ones with red. Unhacked ones are white. One wonders why they didn't just keep up the red-yellow-green scheme of the single player.
* In ''VideoGame/PiratesVikingsAndKnights'', the Pirates are colored red, the Vikings green, and the Knights blue.

[[folder:Hack and Slash]]
* ''{{VideoGame/Gauntlet}}''
** In the arcade version of the original ''Gauntlet'', multiple players could not be part of the same class - they were either, chosen by each player at the start of the game in the 2-player version or assigned by control panel in the 4-player version. This was changed in ''Gauntlet II'', which allowed multiple players to be the same class if they wanted to, distinguishing each player by color-coding their characters. Incidentally, the color-coding in ''Gauntlet II'' matches how the four classes were colored and arranged in the 4-player version of the first game which goes red, blue, yellow and green in that exact order.
** ''Gauntlet Legends'' at first appears to have standard Color Coded Multiplayer, but upon closer inspection, all of the art and in-game models for each color of each character class are radically different, with each color even having something of a theme (e.g. all of the blue characters resemble Western European knights and nobility, the yellow are inspired by Ancient Egypt with a bit of Ottoman Empire, reds are the "generic fantasy barbarian" culture, and greens have a Celtic/Gaelic flair). Each color variation also sports differing costume styles. The reds mostly had fur and were more barbarian-looking; the blues were often more regal and medieval-like; the greens were forest-themed with leather sashes and vests, and the yellows had an Egyptian/desert-themed flair to them.

[[folder:Maze Game]]
* In ''VideoGame/{{Trog}}'', the four players (in the four-player version) control Rex the Red Dino, Bloop the Blue Dino, Spike the Yellow Dino and Gwen the Pink Dino; their respective buttons and joysticks are thus color-coded on the dedicated cabinet.

* ''VideoGame/{{Runescape}}'' differentiates teams in Castle Wars and similar activities with different colors of capes or hats.
* In ''VideoGame/GuildWars'', the two teams in PvP are red and blue. The factions in Factions have red and blue flags to support this. It also tends to refer to objectives in PvP maps by color.

[[folder:Platform Games]]
* ''VideoGame/SuperMarioBros''
** The original ''VideoGame/MarioBros'', ''VideoGame/SuperMarioBros1'', ''VideoGame/SuperMarioBros3'', and ''VideoGame/SuperMarioWorld'' did this with Mario and Luigi. They are identical sprites, but Mario is red and Luigi is green. The exception was ''VideoGame/SuperMarioBros2'', the single-player game that put Luigi on DivergentCharacterEvolution.
** Then ''VideoGame/SuperMarioAllStars'' gave Mario and Luigi different sprites in all of the remakes. In the version of ''All-Stars'' that included ''Super Mario World'', Luigi got a new sprite in that game as well. Some of his actions had to be animated differently in order to keep his hit box intact (for example, he slides on his knees).
** In ''VideoGame/NewSuperMarioBrosWii'', two Toads are color coded yellow and blue, but players can select between them or Luigi (Player 1 is always stuck with Mario, however).
** The "Classic" ''Mario Bros.'' minigame included in the GBA version of ''VideoGame/SuperMarioBros2'' (and with the GBA versions of ''Super Mario World'', ''Yoshi's Island'', and ''Super Mario Bros. 3'', and ''VideoGame/MarioAndLuigiSuperstarSaga'') plays this straight by making all the other player characters (including Luigi) into palette swaps of Mario. Strangely, the Player 3 and Player 4 characters wore Wario's and Waluigi's color scheme respectively (yellow and purple, if with different overall colors).
* ''VideoGame/JazzJackrabbit 2'' had eight customizable colors for six body parts, allowing an almost infinite variety of color-schemes.
* The NES version of ''VideoGame/RushNAttack'' has a 2-Players mode in which Player 1 is in blue and Player 2 is in red, even though both characters are supposed to be Green Berets. The power-up carrying enemy soldiers also happen to be a yellow palette swap of the player as well.
** In ''M.I.A.'', the arcade-only SpiritualSuccessor to ''Rush'n Attack'', Player 1 is green and Player 2 is blue.
* ''VideoGame/KirbysReturnToDreamLand'' lets players be Kirbies of different colors, but they can also choose between King Dedede, Meta Knight, or Waddle Dee, who don't have Kirby's trademark PowerCopying, but they do have [[DropTheHammer their]] [[CoolSword own]] [[BladeOnAStick weapons]].
** ''VideoGame/KirbyAndTheAmazingMirror'' used this trope before it, though it first showed up in ''Kirby's Dream Course''. Also done in the multiplayer portion of ''[[VideoGame/KirbysAdventure Nightmare in Dream Land]]''.
** Similarly, ''VideoGame/KirbyAndTheRainbowCurse'' features multi-colored Bandana Waddle Dees, players three and four being green and yellow, respectively. [[note]] Originally, there would have also been a cyan Bandana Dee, but was [[DummiedOut cut from the final game]]. [[/note]]
* In ''VideoGame/MichaelJacksonsMoonwalker'', the first player controls Michael Jackson in a white suit, the second controls Michael in a red suit, and the third player (available in the UsefulNotes/ArcadeGame only) controls Michael in a black suit.
* ''Shadow of the Ninja'' assigns the first player the purple-clad ninja Hayate and the second player the orange-clad kunoichi Kaede. Their sprites are different, but their movesets are identical.
* The NES versions of ''VideoGame/{{Contra}}'' and ''Super C'' as shown above. Since the NES was unable to produce the same level of detail as the arcade versions, the developers made both characters into palette swaps of the same shirtless commando, with Player 1 (Bill) in the blue pants and Player 2 (Lance) in the red pants.
** The arcade versions of both games used different sprites for each player (Bill had blond hair and wore a tank top, while Lance had black hair and fought shirtless), but they still wore differently colored headbands in the original ''Contra'' (blue for Bill and red for Lance). In ''Super Contra'', Bill wore green and Lance wore purple.
** ''Contra III'' for the SNES, despite being made on a superior hardware than the NES, kept both characters as palette swaps, presumably for tradition's sakes. However, the colors of their combat suits are light green (for Bill) and orange (for Lance) instead of the blue and red they wore in the NES games.
** In ''Contra 4'' for the DS, the four default characters are all palette swaps of the same sprite. Bill and Lance wear blue and red respectively, while their "[[SimilarSquad American counterparts]]", Mad Dog and Scorpion, wear green and purple (a reference to Bill's and Lance's respective colors in ''Super Contra''). The four alternate characters: Lucia, Sheena, Probotector and Jimbo/Sully (the ''Contra III'' versions of Bill and Lance) all have four selectable palettes as well.
** ''VideoGame/HardCorpsUprising'' allows the player to choose from one of five alternate palettes (in addition to the default) in case two players decide to use the same character.
* The arcade version of ''Rastan Saga II'' has {{Palette Swap}}ped CoOpMultiplayer. The most obvious difference between the two characters is skin color, but the indicative colors are gold for the first player and blue for the second player.
* In ''Ninja Crusaders'', the first player controls a red ninja and the second player controls a blue ninja.
* The two teams in ''VideoGame/KillerQueen'' are identical sprites with blue or gold color schemes.

[[folder:Puzzle Games]]
* Two-player mode in the Amiga version of ''VideoGame/{{Lemmings}}'': one player controls the blue lemmings, the other player the green lemmings, and each player's goal is to ensure that as many as possible (regardless of colour) enter that player's exit, also colour-coded.
* ''VideoGame/HelterSkelter'': The first player controls a red ball, and the second player controls a blue one.

[[folder:Real-Time Strategy]]
* ''VideoGame/AgeOfEmpires'' gives you two options for this: Either each team can have a different color or all your enemies can use a single color different from yours.
* ''VideoGame/{{Starcraft}}'' has this too. There are eight colors available, and you can be any of those colors (race does not matter). Color coding also happens for single player.
* Ditto for the numerous ''VideoGame/CommandAndConquer'' games, where usually 8 colours are selectable.
* ''[[Videogame/BattleZone1998 Battlezone II]]'''s Strategy and [[CoOpMultiplayer MPI]] gamemodes default to Team 1 having red units and Team 2 having blue units. Free-for-all strategy has Yellow and Green. In deathmatch, each player is given a random color at the start of the round - every player fears the neon pink [[HumongousMecha Attila]].
* ''VideoGame/{{Pikmin}} 2''[='=]s battle mode sets one player as Olimar (who has a slight red scheme) and gives him an army entirely made of Red Pikmin, with the other player as Louie (who has a slight blue) with Blue Pikmin. The third game, where each player may now have a mix of colors to get, colors the Pikmin's stems with cyan or magenta and uses these colors for the player.
* ''Videogame/WarcraftII'' attributed a separate faction (though the game wasn't advanced to support every faction's individuality like naval units or mages) to each color: red orcs were Blackrock, blue humans were Stormwind, purple humans were Dalaran while purple orcs were Twilight's Hammer, etc.
* ''Videogame/WarcraftIII'' has twelve colors (and black, usually reserved for neutral units but units can be made to appear one color), but the colors can be swapped out in-game to blue for your units, teal for allies, and red for enemies regardless of ownership.

[[folder:Role-Playing Games]]
* ''VideoGame/DragonQuestWars''.
* In ''VideoGame/DokaponKingdom'', players who share the same class look identical, other than color and gender. You can go to the barbershop and get a new hairstyle, but it is sometimes lost upon death.

[[folder:Rhythm Games]]
* The ''VideoGame/JustDance'' series of games, Usually in Duet and Dance Crew songs, but the majority have visually distinctive dancers.
* Multiplayer in ''VideoGame/UmJammerLammy'' has Player 1 as Lammy and Player 2 as Rammy, a gray-scale PaletteSwap of Lammy (though she is her own character).
* ''VideoGame/ReflecBeat''[='=]s two sides are distinctly labeled "red side" and "blue side", although "red" in this case looks more like pink.

[[folder:Shoot 'em Ups]]
* ''VideoGame/{{Touhou}}'' fighting games ''Immaterial and Mising Power'' and ''Scarlet Weather Rhapsody'' have an alternate palette for each character. ''Hisoutensoku'' amps it up by having eight palettes per character.
* ''[[VideoGame/{{Gradius}} Salamander]]'', a spinoff of the original ''Gradius'', has one player piloting a blue ship and the other player a red ship. These ships were later identified as the Vic Viper from the original ''Gradius'' and the newly-introduced [[ShoutOut Lord British]] (or [[SpellMyNameWithAnS Road British]], as it was called in the localization of the NES port) and they actually have different sprite designs in the arcade version. The Lord British would later appear as a selectable ship in ''Gradius Gaiden'' for the [=PlayStation=].
** The MSX version of ''Salamander'' replaces the Vic Viper and Lord British with the Sabel Tiger and the Thrasher.
** ''Gradius V'' would be the first game in the mainline series to have 2P co-op. However, the second player's ship is a red-colored Vic Viper (the Model T-301 to be precise) rather than a Lord British.
* The ''VideoGame/{{Raiden}}'' series features a red Raiden and a blue Raiden. ''VideoGame/RaidenFighters'', on the other hand, [[DivergentCharacterEvolution make the red Raiden (Raiden mk-II) and blue Raiden (Raiden mk-II Beta) play differently]].
* The cooperative 2-player mode of ''VideoGame/TwinCobra'' gives the first player a red helicopter and the second player a blue helicopter. These were {{Palette Swap}}s of each other, but they received DivergentCharacterEvolution in ''Twin Cobra II''.
* In the ''VideoGame/{{Twinbee}}'' series, the players' ships are Twinbee (blue), Winbee (pink), and Gwinbee (green).
* In ''Gokujou VideoGame/{{Parodius}}'', all the Player 2 characters are all differently-named {{palette swap}}s of the Player 1 characters using the same weapon sets. However, ''Sexy Parodius'' gave the Player 2 characters slightly different weapon sets.
* In ''VideoGame/AegisWing'', the four ships are distinguished only by color.
* In ''VideoGame/IkariWarriors'', both players are shirtless men with black hair and pants. Player 1 (Ralf Jones, or Paul as he was called in the [[DubNameChange NES localization]]) wears a red headband reminiscent of [[Franchise/{{Rambo}} John Rambo]] while Player 2 (Clark Still, a.k.a. [[DubNameChange Vince]]) wears a blue headband.
* In ''VideoGame/JamestownLegendOfTheLostColony'', each player has an aura that is red, blue, yellow or green depending on the player.

[[folder:Sports Games]]
* The multiplayer for the new ''VideoGame/PunchOut'' has Mac fighting a clone of himself in different clothes. Doc Louis even lampshades this.
* In ''VideoGame/WiiSports'', Player 1 is colored blue, Player 2 is red, Player 3 green, and Player 4 yellow.
* In ''VideoGame/{{Speedball}}'', the Player 1 team wears green, and the computer or Player 2 team wears red. ''Speedball 2: Brutal Deluxe'' changed the Player 1 color to blue, and added colored indicators and health bars to make the difference more obvious.
* In Creator/{{Konami}}'s ''Escape Kids'', the players are coded not only by color, but also by nationality. Player 1 (blue) is Syd Jones from the United States, Player 2 (yellow) is Dio Vitale from Italy, Player 3 (green) is Jya Aziz from India, and Player 4 (red) is Ken Kosugi from Japan.

[[folder:Turn-Based Strategy]]
* The ''[[VideoGame/NintendoWars Advance Wars]]'' series has its ColorCodedArmies. Multiplayer modes decide the colors from which slot each person is using.
* The Link Arena mode in the UsefulNotes/GameBoyAdvance ''VideoGame/FireEmblem'' games assigns blue units to the first player slot, green units to the second slot, red units to the third slot, and purple units to the fourth slot.

[[folder:Third-Person Shooter]]
* ''VideoGame/DestroyAllHumans 2''.
* In ''VideoGame/MindJack'', players on your team are blue 'wanderers', players on the enemy team are red. When in control of an {{NPC}}, the respective colour outlines the {{NPC}}.
* While ''VideoGame/TransformersWarForCybertron'' didn't use this, having players choose separate models and colors for the Autobot and Decepticon versions of their classes, the sequel ''[[VideoGame/TransformersFallOfCybertron Fall of Cybertron]]'' does use this; one creates just one model for a class and differentiates the Autobot and Decepticon versions of it by picking from different pools of palette options. Also, the game automatically swaps voices and TronLines colors based on faction, with there being an option to use player-relative colors (blue = allies, red = enemies, regardless of faction) or absolute colors (red = Autobots, purple = Decepticons, regardless of which team the player is on).
* ''VideoGame/S4League'' is a little weird with this. Players on your team will have their equipment rendered with their natural colors which can be blue, yellow, green, or purple. Players on the opposing team will have their equipment {{Palette Swap}}ped to be red. In Battle Royale, a free-for-all mode with no teams, ''all'' other players will be wearing red. As a result of this POV-based color-coding system, equipment that is naturally red does not exist.

[[folder:Miscellaneous Games]]
* In ''VideoGame/GliderPro'', the second paper airplane is folded from a yellow sheet instead of a white one. However, these use completely different sprites, because all the game's graphical resources have to share the same 256-color palette.
* In the Versus Mode of ''VideoGame/MetalGearGhostBabel'', the second player controls another Solid Snake clad in a red sneaking suit instead of the blue one wore in the story mode.
* ''Vindicators'' made the first player blue and the second player red, right down to the control panel on the original arcade cabinet.

* Duplicate monsters in ''Anime/FutureCardBuddyfight'' are recolored. Justified InUniverse via AmazingTechnicolorPopulation.

[[folder:Tabletop Games]]
* In the Franchise/DisneyPrincess edition of the board game ''Pretty Pretty Princess'', all the player pieces are [[Disney/SleepingBeauty Aurora]] in her [[GemEncrusted bejeweled]] [[PimpedOutDress dress]], with one being pink, another blue, another purple, and the fourth gold.
* The pieces in just about any board game by Milton Bradley or Parker Brothers will have players coded Red, Blue, Green, Yellow:
** ''Trouble''
** ''Sorry!''
** ''Mouse Trap''
** ''TabletopGame/CandyLand''
* In TabletopGame/{{Chess}}, the leading player is the white side, while the other player is the black side.
* The color coding in TabletopGame/{{Go}} is inverted from that of chess: The leading player is the ''black'' side instead.

* In ''Webcomic/ElGoonishShive'', when Nanase creates one shadow copy of herself, the copy is colored with one of the primary additive colors (red, green, or blue), while Nanase is colored with the corresponding primary subtractive color (cyan, magenta, or yellow, respectively). This actually [[ShownTheirWork makes sense from a scientific standpoint]]: the real Nanase is absorbing the color the fake one is producing.
* ''Webcomic/CtrlAltDel''[='s=] "Players": [[OnlySaneMan One]] is blue, [[FieryRedhead Two]] is red, [[NonActionGuy Three]] is yellow, and [[PsychopathicManchild Four]] (the [[TheChick lone girl]]) is green.

* ''Machinima/RedVsBlue'' started out as merely a parody of this trope. [[spoiler:Later, the Reds and Blues discovered that the two armies who were pitted against each other were just simulations for Freelancer Agents to train. Which finally, after most of eight seasons, actually hit the Reds' and Blues' BerserkButton.]]

[[folder:Real Life]]
* OlderThanFeudalism: Ancient Roman chariot races had four teams, using almost exactly the same colors as today: Red, Blue, Green, and White. From the normal seats, color was the only way to tell who was who. Unlike modern sports teams, which have actual names instead of just team colors, the color was all that identified the factions.
** This distinction carried over to Byzantine chariot races. The supporters of Blue and Green--the biggest teams--eventually got mixed up in political, religious, and social disputes, and their ''demes'' (fan clubs, basically) became, in effect, street gangs-cum-political parties. Tying fully into this trope, each ''deme'' wore the colors of its team (Blue supporters wore blue and Green supporters wore green). This led to the [[http://en.wikipedia.org/wiki/Nika_riots Nika riots]] of 532, when the Blues and Greens teamed up in protest of the emperor's actions to keep their roiling culture in check.
* In RealLife sports, if two teams have primary jerseys with the same colors, one is forced to use the secondary kit. In most North American sports, the issue is avoided entirely as the home team traditionally wears its colored uniform while the road team wears its white uniform. There are a few exceptions to the color-at-home rule:
** In basketball, the home team wears white while the road team wears a dark color. The most famous exception to this rule is the Los Angeles Lakers, who traditionally wear gold at home, except for Sunday games when they wear white.
** In baseball, the home team wears white while the road team wears gray, which can get even more complicated because baseball teams also wear colored jerseys. However, even when wearing colored jerseys, one constant remains: The home team wears white pants while the road team wears gray pants.
** In college and minor league hockey, the home team wears white while the road team wears their colored jersey, which is the inverse of what the NHL does.
** Variants in casual sports include single color\multicolor (if the other team doesn't have a uniform - though it's asked for everyone who is wearing the same color as the adversary to get another shirt), and shirtless\shirt on.
* Boxing, professional wrestling and other ring sports typically have competitors in the Red Corner and the Blue Corner.
** For martial arts, the competitors wear different colors: Olympic (Greco-Roman) wrestling has red or blue singlets, Judo has white or blue ''dōgi'', and Taekwondo has red or blue helmets/pads over white ''dobok''.
* While not related to ''uniforms'', several game shows have seated their contestants behind red, yellow, and blue podiums. A notable example is ''Series/WheelOfFortune''. Some have red and blue podiums, like ''Series/CardSharks'', for example.
** The Japanese quiz show ''Series/PanelQuizAttack25'' takes this one step further and refers to the four players by their colors--Aka (red), Midori (green), Shiro (white), or Ao (blue)--rather than their names, when buzzing in.
