So, our heroes are fighting with TheDragon. The ActionGirl activates her LimitBreak and starts glowing violet. The SmartGuy unleashes his DangerousForbiddenTechnique and becomes [[HulkingOut all covered in green]]. Their combined attack badly damages TheDragon, but in response, he TurnsRed - literally, as his transformation changes all his colors to red. But fear not! TheHero enters SuperMode with his body turning all gold from awesome power and is ready to unleash it all to deliver the final blow...

A shapeshifting trope without an actual change in shape, this is when a character's transformation to a new form is indicated by a change in hair and clothing color, which is meant to symbolize the power. Sometimes, character is just [[PowerGlows shining with one-colored aura]] and sometimes, [[ConvenientColorChange all his color temporary changes into that one.]] It's clear indicator for the audience that, that character is now getting stronger. [[RuleOfCool And it looks damn cool]].

It very often overlaps with PowerGlows, especially in SuperRobot shows, but there are cases of one that does not require the another.

May be a visual indication of HeroicRROD, SuperMode, or TurnsRed. Compare with VolcanicVeins, TronLines, BattleAura, PowerTattoo, MarkOfTheBeast, MarkedChange and GoldenSuperMode. See also ColourCodedForYourConvenience and ConvenientColorChange.



[[folder: Anime & Manga ]]

* Anime/GaoGaiGar turns green whenever it uses [[YinYangBomb Hell And Heaven]] and gold when using [[DropTheHammer Goldion Hammer]]. Mechas affected by '''THE POWER''' shine orange. Gai himself has [[SuperMode Hyper Mode]], which turns all his body armor, as well as his hair, gold.
* ''Manga/{{Heroman}}'' turns red whenever he enters [[UnstoppableRage Rage]] [[SuperMode Mode]]. [[spoiler: So does Joey]].
* When [[Anime/{{FLCL}} Canti]] combines with Naota, it turns red. [[spoiler:Naota also turns red after temporarily absorbing Atomsk's powers]].
* In ''Anime/MobileFighterGGundam'', powerful warriors turn themselves and their mecha gold when they use their most powerful attacks.
** ''Anime/MobileSuitGundam00'' has the Trans-Am system, which triples the machine's abilities while also turning it bright red.
* ''Anime/TengenToppaGurrenLagann'' uses it too, a few times.
* ''Franchise/LyricalNanoha:
** When Subaru synchronizes her {{Power Fist}}s in ''Anime/MagicalGirlLyricalNanohaStrikers'' (by slamming them against each other, no less), allowing her to use [[DualWielding both at the same time]], the right gauntlet (originally her sister's) turns from white purple to her native black and blue.
** In ''Manga/MagicalGirlLyricalNanohaViVid'', [[spoiler:Vivio's white jacket turns to its original black color when she changes from her Adult Mode to her Sankt Kaiser Mode.]]
* In ''Manga/OnePiece'', when Luffy uses Gear 2nd, his skin color becomes pink, due to all the blood being pumped rapidly through his body.
* ''Manga/{{Naruto}}'''s eponymous character has [[RuleOfThree three]] (so far, anyway). His eyes are blue in the normal mode, turn red in SuperMode No. 1, and Orange in SuperMode No. 2. [[spoiler: His whole body turns [[GoldenSuperMode gold]] and black in SuperMode No. 3]].
** Justified when Lee and Guy open their Gates. The third gate turns their skin red due to the increased blood flow; the seventh gate causes them to generate a green aura as their sweat immediately evaporates from their skin; and the eighth gate turns the aura red from their ''[[HeroicRROD blood literally boiling in their veins]]'', with their body eventually turning black as it cooks itself.
* In ''Anime/RebuildOfEvangelion'', Evas that undergo pseudo-evolution due to consuming an Angel turn into a glowing, white EnergyBeing. Additionally, Unit 01's eyes and neon lights (both green) turn red, its mouth emits a red glow and its skin a yellowish glow when it's on the verge of reaching pseudo-evolved state; [[spoiler:Unit 13 just straight skipped to the EnergyBeing phase]]. In any case, an Eva undergoing these changes is a major MassOhCrap - even to those who haven't seen the original series. [[LightIsNotGood And as it turns out]], [[TheEndOfTheWorldAsWeKnowIt for good reason]].
** In the third movie, [[spoiler:Eva Mark.09 turns dark gray-brown with a hint of red when it reverts to its Adams' Vessel state and grows a new head with ten glowing red eyes instead of the mechanical-looking [[CyberCyclops Unit 00 lookalike]] it had]].
* ''Manga/DragonBall Z'': Kai-O-Ken turns the user's body flush with red, with a red aura, and Super Saiyan at the very least turns the fighter's hair gold with a gold aura. And then there is Frieza's "Golden Frieza" form, which is ExactlyWhatItSaysOnTheTin.
* In ''Anime/YuGiOh5Ds'', [[spoiler:Yusei turns gold when he uses Over Top Clear Mind]].
* Kaito Tenjo from ''Anime/YuGiOhZEXAL'' engages in Photon Mode whenever he duels, turning all his clothes completely white.
* In ''Manga/YuYuHakusho'', Toguro turns dark purple when he uses 100% of his power.
* In ''Manga/SaintSeiya'', after the Asgard arc, the Bronze Saints experience this with their Cloths turning an awesome shade of Gold (most of the time with a ThemeMusicPowerUp) when they properly use their full powers. Doubles as a CrowningMomentOfHeartwarming and TakingUpTheMantle for TheAtoner Gold Saints.
* Various ''Franchise/PrettyCure'' girls get to change colors from time to time with their Super Modes. The second ''Anime/FutariWaPrettyCureMaxHeart'' movie had the girls turn gold, the ''Anime/YesPrettyCure5GoGo'' movie had Shining Dream's form be a subdued pink and the Super Silhouette forms in ''Anime/HeartcatchPrettyCure'' are extremely subdued in color to the point where it's almost completely white.


[[folder: Comic Books ]]

* The Comicbook/IncredibleHulk, of course - when Banner turns into the Hulk, his body changes color to green, or sometimes gray. Jen Walters' ComicBook/SheHulk turns green as well (and has occasionally gone gray), while Rick Jones as A-Bomb turns blue, Hulk's son Skaar turns into a gray shade of green (so he is often gray or green, depending on the colorist), and ComicBook/RedHulk and Red She-Hulk turn...[[CaptainObvious red]].


[[folder: Live Action Television ]]

* The ''Franchise/UltraSeries'' has this trope in spades.
** Whenever Series/UltramanTaro uses his Storium Beam, he raises his arms into the air and briefly goes through all the colours of the rainbow while drawing in energy.
--->'''"STORIUM KOHSEN!"''' ''[[UnsoundEffect VOOOOOORP]]'' [cue the beam]
** Series/UltramanTiga changes colour when he changes type. It should be noted that Tiga's Multitype bears a variety of colours. If he changes to his Power Type, he turns red, while in Sky Type his colours are predominantly purple. If he assumes his Glitter Type, which is his strongest form, he becomes gold.
** Series/UltramanDyna continues this theme. His Miracle Type state involves him assuming a white and sky blue colour, while his Strong Type features a more red-based colour scheme.
** ''Series/UltramanCosmos'' takes this a step further by assigning different emotions to Cosmos's Forms. When Cosmos is in his default blue Luna Form, he tries to end fights peacefully and spare his opponents. When he has no choice or is fighting a blatantly-evil foe, he literally TurnsRed and assumes his Corona Form. In this form, he's far more willing to dish out some damage.
* Very common with modern Franchise/{{Kamen Rider}}s. Here's just a few, and many follow the LawOfChromaticSuperiority.
** ''Series/KamenRiderKuuga'' started it. ''Series/KamenRiderBlackRX'' may have begun form-changing in its current form, but ''he'' got ''total'' redesigns. Kuuga gets a rainbow of colors and only a few small design changes.
** With ''Series/KamenRiderKiva,'' only his chest and the limb that holds the weapon change color.
** Series/KamenRiderHibiki becomes red in his Hibiki Kurenai form.
** The red-and-black Series/KamenRiderFaiz goes all-black with white accents for Accel Form and all-red with black accents for Blaster Form.
** From ''Series/KamenRiderDouble'', ''half'' of Double's suit changes, as he's made of two guys and each has access to (initially) three forms. The different forms affect each other so that the same power will be wielded in different ways (for example, Joker makes it so that a power is applied to the body. Trigger has a gun. Luna Joker has stretchy limbs. Luna Trigger does ''not,'' but the shots from the Trigger Magnum will bend to hunt down targets.)
*** Kamen Rider Accel from the same series starts out as red, then gets a SuperMode that turns him blue (after briefly turning yellow as part of a traffic-light motif). In the post-series movie, he gets another upgrade that's [[GoldenSuperMode gold]] / yellow.
** ''Series/KamenRiderOOO'' has different forms for head, body, and legs, seeming to be the writers saying "if two was cool, three is better!" However, Eiji's leg form won't do something different depending on his head form. He must still decide which three powers complement each other best and are right for the job. Three of the ''same'' color is extremely powerful, but extremely taxing.
** ''Series/KamenRiderFourze'' normally has a white suit, with power-up forms in red [Fire], gold [Elek], silver [Magnet], and blue [Cosmic]. His movie-exclusive Rocket States plays this trope even closer, being a palette-swapped version of his regular suit into orange.
** ''Series/KamenRiderWizard'' takes this to massive extremes. His base form is black with red [Fire], blue [Water], green [Wind] or yellow [Land] gems. Dragon Styles reverse this. Infinity turns him silver. Infinity Dragon Gold Mode turns him Gold.


[[folder: Video Games ]]

* In {{VideoGame/Vindictus}}, the transformations. No matter what your character looked like before, dark knights have a black with red motif, and paladins have a white with blue one. The exception is certain armor sets, which are modeled after the appearance of the transformations and don't visually change much.
* Super Sonic and the other SuperMode characters from ''Franchise/SonicTheHedgehog''.
** With the two notable exceptions of Tails and Knuckles, who either just glow or gain auras around themselves.
* Biotics in the ''Franchise/MassEffect'' saga tend to glow blue when using powers or using amazing Asari biotic acrobatics.
* In ''VideoGame/SuperRobotWarsJudgment'', [[Anime/MartianSuccessorNadesico Akito and Gai]]'s mechas turn gold when they use their team-up attack.
* Grabbing an [[InvincibilityPowerUp invincibility star]], causes [[SuperMarioBros Mario]] to flash a rainbow of colours until the effect wears off.
** Several other powerups change the color of Mario's shirt and overalls including Fire (red on white), [[VideoGame/NewSuperMarioBrosWii Ice]] (red on light blue), and [[VideoGame/SuperMarioGalaxy Flying]] (black on red). Luigi swaps out the red in these transformations for green but otherwise the same applies for him.
* A variation of this: in ''VideoGame/{{Caster}}'', the protagonist appears in a certain colour depending on the currently selected spell.
* In ''VideoGame/TheLegendOfZelda'', there is a magic ring that reduces damage. It also changes Link's clothes from green to light blue. An even better ring makes them red. Due to a programming quirk, the merchant's and some other character's clothes also change color to match.
** In ''VideoGame/ZeldaIITheAdventureOfLink,'' the shield spell turns you red. As above, anything that's the same shade of green as your tunic will change with you, even undergoing the very same flicker!
** In ''VideoGame/TheLegendOfZeldaOcarinaOfTime,'' you get the Zora Tunic that lets you breathe underwater and the Goron Tunic that lets you withstand heat (though ''super''-hot things like standing in lava will just hurt you ''less.'') And again, other things of the same color are subject to the glitch (Aveil's clothes ''and lipstick'' will change with your tunic. Her ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'' appearance and remakes of OOT for more modern systems have her tunic and lipstick as always red.)
** In ''Majora's Mask'', when Link becomes the Fierce Deity, he doesn't just get a new color scheme, but an elaborate new outfit, with armor, a {{BFS}}, and FacialMarkings. This has been Link's strongest transformation so far.
* The Trance ability in ''VideoGame/FinalFantasyIX''. Zidane's skin (or fur, [[DontExplainTheJoke since he looks like a monkey]]) changes to pink. Vivi's clothes change to white. Steiner's armor gets green details. Freya's clothes change to purple. Quina's skin color changes to black. Eiko gets white clothing and yellow hair. Scarlet Head Amarant becomes [[IncrediblyLamePun Purple Head Amarant]]. Garnet gets pink skin and yellow hair and clothes. [[BigBad Kuja]]'s purple robes and silver hair both [[TurnsRed turn red]]. Unlike the other examples, [[OneWingedAngel this is not a good thing]].
** Unlike other examples, the characters also undergo costume alterations in addition to color alterations, some minor (Vivi's hat straightens out, Steiner gets a faceplate for his helmet, the wings on Eiko's costume grow), some major (Amarant and Zidane lose their clothes entirely, while Freya's outfit upgrades into a full set of plate armor, including, gauntlets, greaves, and a face-concealing helmet).
* The bosses in ''VideoGame/TheSimpsons'', after enough hits.
* In ''VideoGame/KidIcarus'', Pit changes colors as he levels up.
* Princess Shroob from ''VideoGame/MarioAndLuigiPartnersInTime'' literally TurnsRed halfway through the battle, increasing the speed and frequency of her attacks.
* [[Franchise/DevilMayCry Dante]] and [[VideoGame/GargoylesQuest Firebrand]] do this as Hypers in ''VideoGame/MarvelVsCapcom3''.
* In ''[[VideoGame/BombJack Mighty Bomb Jack]]'', Jack turns blue, orange and green with increasing levels of Mighty Power.
* As of an update to ''VideoGame/{{Skullgirls}}'' ''[[UpdatedRerelease Encore]]'', [[SNKBoss Marie]] changes to a [[OfficialFanSubmittedContent backer-submitted]] alternate palette when encountered on [[HarderthanHard Nightmare difficulty]] of Arcade mode or [[spoiler: as Marie 300% in Squigly's joke story mode]].
* In the video game for ''Series/MightyMorphinPowerRangers'', (both the UsefulNotes/SuperNintendo and UsefulNotes/SegaGenesis versions), Cyclopsis will turn gold when he powers up to his second form.
* In VideoGame/BreathOfFireIII, Ryuu's ultimate dragon form, the Kaiser, simply turns him gold while pumping up his stats and giving him new powers in addition to the Skills he already knew.
* Jack Frost, the cute blue-and-white MascotMook of the ''Franchise/ShinMegamiTensei'' series, can permanently transform into the menacing Black Frost through ThePowerOfHate. You can actually see this happen in ''VideoGame/DevilSurvivor'', and then recruit him into your party. And if you then take the [[spoiler: Demon Overlord]] ending, you see this made him powerful enough to [[spoiler: ''become your [[TheDragon Dragon]]'']].


[[folder: Web Comic ]]

* In a reference to the Comicbook/IncredibleHulk, Thog the half-orc from ''WebComic/TheOrderOfTheStick'' normally pale green skin turns a deeper emerald shade when entering his barbarian rage and his pants randomly turn purple (regardless of their original color).
* In ''Webcomic/CogaNito'', [[spoiler: Eric goes from RedIsHeroic to BlueIsHeroic when he uses the Heart to power up.]]


[[folder: Web Original ]]

* When WebVideo/TheIrateGamer powers up using his sword, his shirt changes from blue to red.


[[folder: Western Animation ]]

* In ''WesternAnimation/{{WITCH}}'''s second season finale, [[spoiler: when girls turn into incarnations of their elements]], it comes with a change of their appearance, including colors.
* Happens in the climax of the GrandFinale in ''WesternAnimation/AvatarTheLastAirbender'' when Aang starts spiritbending.
** Likewise, in ''WesternAnimation/TheLegendOfKorra'', Korra's use of spiritbending in the finale of Book 2 turns her blue, while her enemy, [[BigBad Unavaatu]], turns black and red. And, as a bonus, [[{{Kaiju}} they also turn 20 stories tall!]]
* Happens in a rather creepy fashion in season 2 of ''WesternAnimation/{{Wakfu}}'' when [[spoiler:Qilby reveals his true nature and merges with the Eliacube, turning his skin bone white in the process.]]


[[folder: Real Life ]]

* Humboldt squid turn red when angry.
