** In at least one source (Sonic CD) it is stated that sonic's trademark blue quills became that colour the first time he ran at sonic speeds.

* In the latest chapter of ''{{Bleach}}'', [[spoiler: Ichigo's hair turns black when he activates the Final Getsuga. Not only that, it overlaps with [[PowerMakesYourHairGrow Power Makes Your Hair Grow]]]]. [[spoiler:It's not so much power as a TimeSkip brought on by YearInsideHourOutside.]]

* ''SonicTheHedgehog'' has his Super Form; after collecting the seven Chaos Emeralds, he turns gold and is basically invincible. Knuckles similarly goes from red to green.

!!Examples:

* ''SonicTheHedgehog'' has his Super Form; after collecting the seven Chaos Emeralds, he turns gold and is basically invincible. Knuckles similarly goes from red to green.
* ''Disgaea 2'' does this with [[spoiler: Rozalin, when she reverts back to her Overlord Zenon state.]]
* ''DannyPhantom'' has his human side with black hair, his ghost half with white.
* In ''{{Darker Than Black}}: Gemini of the Meteor'' Izanagi [[spoiler:[[MindScrew sort of]] formerly known as Yin,]] has [[PowerGlows fluorescent]] [[YouGottaHaveBlueHair blue hair]] where once she had more standard [[spoiler:bluish-white hair]], because she is now an [[spoiler:ApocalypseMaiden]].
* ''PrettyGuardianSailorMoon'': The characters all have normal hair in civilian ID and it turns brightly colored when they [[TransformationSequence transform]].
* In MarvelComics ''[[http://www.marvunapp.com/Appendix/generic.htm Generic Comic Book]]'' TheHero's hair turned white when he got his superpowers.

* In ''DragonQuestVIII'' when the main character builds his tension high enough his hair becomes lighter and spiky. Not that strange considering that AkiraToriyama did the character designs.
* In the original ''LastBlade'', Kaede can awake his inner powers and become more powerful, faster and blond. He keeps that guise for the second installment of the series.
* On ''BuffyTheVampireSlayer'', after [[spoiler:Tara dies, Willow's]] normally red hair turns black, as do [[BlackEyesOfEvil her eyes]]. Conversely, when she [[spoiler:activates all the slayers]], her hair briefly goes white. Basically, she's ColourCodedForYourConvenience to indicate if she's casting good or evil magic.
* Negi Springfield of ''MahouSenseiNegima'' has his hair turn white during his [[{{Supermode}} Magia Erebea]]. Not quite sure why.
** [[WhiteHairedPrettyBoy Isn't it obvious?]]
** [[spoiler: Mana Tatsumiya]] has her hair turn white when releasing her full power.
* The mages in ''MagicalGirlLyricalNanoha'' when they fuse with either Rein or Agito.

* ''{{Tsukihime}}'': In the game at least, [[spoiler: Tohno Akiha's]] hair changes to a bright red when her SuperpoweredEvilSide comes out.
* More subtle example -- in ''{{Yu-Gi-Oh}}'', when Yugi switches to Yami Yugi, lightning bolts of blonde hair extend upwards from his bangs that aren't there as regular Yugi.
* Susan from ''MonstersVsAliens'' became a WhiteHairedPrettyGirl after exposure to AppliedPhlebotinum, although when BroughtDownToNormal she retained the hair color.

* ''TheKingOfFighters'': When the Orochi blood of Leona Heidern takes control of her, she awakes her SuperpoweredEvilSide and her hair changes from blue to red.
* In ''{{Xenogears}}'', Fei Wong's hair is dark but [[spoiler: turns red when he becomes Id.]]
* In the anime version of ''TokyoMewMew'', Ichigos's TransformationSequence, in addition to turning her into a CatGirl and giving her nice MagicalGirl clothes, changes her hair from dark red to pink, and the rest of the girls also have their hair colors changed to brighter shades. Another example, present in both the anime and the manga, is [[spoiler: dark-haired Aoyama Masaya transforming into the blonde MysteriousProtector Blue Knight]], which is slightly odd, because [[spoiler:as the BigBad Deep Blue, he has black hair again]]; though this one has an excuse of being a part of the RedHerring designed to conceal the character's identity ''from the audience'', not just from the characters.
* Amongst the various other effects of becoming a Succubus in ''FanFic/TheReturn'' is an instant dye job on the hair.
* In MercedesLackey's world of [[HeraldsOfValdemar Velgarth]], sufficient magic use will not only bleach a mage's hair prematurely white, it will also turn his eyes blue. This is why [[spoiler:the Companions are gleaming white and have blue eyes]].
* Played with in ''ElGoonishShive'', when ''losing'' her magical abilities turns Nanase's hair black.
** And then played (relatively) straight when Susan's magical awakening turns Susan's hair dark blue … in large part ''because'' that was the color that she was already dyeing it.

* In the latest chapter of ''{{Bleach}}'', [[spoiler: Ichigo's hair turns black when he activates the Final Getsuga. Not only that, it overlaps with [[PowerMakesYourHairGrow Power Makes Your Hair Grow]]]].
** [[spoiler: It's not so much power as a TimeSkip brought on by YearInsideHourOutside.]]
* Let's not forget ''TheSlayers'', where Lina's [[DangerousForbiddenTechnique Giga Slave]] leaves her [[FieryRedhead red hair]] a platinum blonde so light it's almost silver for a day or so after she casts it. Not to mention that time it [[PowerGlows glowed golden]] because [[spoiler:the spell involves channeling the Lord of Nightmares, who replaced her soul when it backfired]].
* This tends to happen in the ''PrettyCure'' franchise--in addition to getting absurd hairstyles, Pretty Cures' hair gets a lot brighter in color--a great example is in ''FreshPrettyCure''.

* Variation: The wings of “Charcoal Feathers” in ''HaibaneRenmei'' slowly turn from light charcoal grey to inky black if [[spoiler: they become by “sin bound” by doing poorly in their RedemptionQuest]].

* In Breath Of Fire 3, turning into a Kaiser form causes the main character's hair to turn gold and sparkle.
* In ''MonochromeFactor'' whenever Akira becomes a Shin his hair turns black.
