You Gotta Have Blue Hair - Television Tropes & Idioms

At any rate, would not a list of anime WITHOUT implausible colors be the shorter list?
Urusei Yatsura has green-haired characters, though this is justified because they're aliens. The humans all seem to have natural hair colors.
- In the color-pages of the manga, unlike in the manga, Lum's hair is actually rainbow-colored.
Subverted/deconstructed in Kemono No Souja Erin, as while Erin and her mother both have (impossibly) naturally green hair, other people notice, and it marks them as part of a village associated with black magic and general creepiness.
Chirico from Armored Trooper VOTOMS has blue hair, along with a few other minor characters. Most of the other major characters have normal hair colors, though.
Dragon Ball Z Has Bulma, with blue hair. Oddly enough, this editor remembers a line from Dragon Ball Z lampshading the improbability of blond hair in Japan, but nobody ever mentions anything else. Trunk gets his purple hair from his grandfather and it turns gold when he's Super Saiyan.
- The line in question was lampshading the Super Saiyan's inexplicable hair color change. Chichi threw a hissy fit over her son and husband coming home with blond hair, thinking they dyed it and joined a gang.
  - There was an old couple that saw Goku on the TV during the Cell Game and were like "Isn't that Chichi's husband that dyed his hair recently and wears those funny clothes?"
- Strangely enough, Bulma has actually dyed her hair a few times — each time to a color equally as weird as her natural color.
- In the manga, her hair is as purple as her father's, if not slightly darker, as well as Bra's. They probably colored their hair as that teal tone in anime to show how much the women in Briefs family worry about beauty since a young age, and dye their hair to prove so.
- Also, in the anime, as opposed to manga, Lunch (when not in Kushami form, there she's a rebel blonde that makes blonde-haired people keep their bad fame) doesn't have a black hair with a bluish tone, but dark blue hair instead, almost like the print media example. Seems like Toriyama probably planned her to have, indeed, dark blue hair, but painted it black in the manga to save reticulum patterns (since her hair would be so dark it would be unnecessary), not the other way around. You can see that she keeps that consistent design through the series before she disappears, as opposed as one-time colorings, like Chichi's or even Goku's.
Gundam Seed very carefully and deliberately averted this trope by giving unusual hair and eye colors ONLY to Coordinators, genetically engineered humans, while Naturals, those without genetic modification, had only natural hair and eye colors. The sequel, Gundam Seed Destiny, almost immediately screwed this up with Sting and Auel, Naturals with green and blue hair respectively.
- Used as a plot point in the spinoff manga Gundam Seed Astray: the mercenary Kaite Madigan is a Coordinator whose parents abandoned him because, due to a genetic defect, his facial hair is a different color from the hair on his head.
- Gundam 00 seems to also have done this, where the only people with oddly colored hair (light/dark purple, pastel green, blue) are genetically-engineered Innovators and Ribbons' children, the Trinities, or experimentally modified Super Soldiers, making them easy to spot from a mile away. Having rather odd names (by Real Life standards) also does a good job of spotlighting them.
  - Feldt, a normal human, has bubble-gum pink hair, but it turns out she dyes it out of a complex from having been raised in space unlike other people.
Sailor Moon has characters with huge amounts of weird hair colors.
- In one of the manga side stories (and the anime special based on it) Chibi-Usa's new classmates actually point out that she has pink hair, which is apparently unusual from the characters' point of view. Makes one wonder if everyone else's hair colors are real, and if so, why nobody finds them odd. Is it only pink that is considered weird?
  - Which pink is actually the closest to a real color you could get out of the series. Hasn't anyone ever heard of strawberry blonde?
- In the Sailor Moon manga, Sailor Jupiter has curly auburn hair. In chapter five, when one of the teachers confronts her for it, she insists that it's natural.
- The live-action version made their signature hair part of their costumes.
  - Which was the creator's original intention. She had wanted the girls to all have more natural hair colors that would then turn into the fantastical rainbow hairstyles when they transformed. It was supposed to add to the disguise as well as accentuate the magic involved in their transformations.
The titular character of Yu-Gi-Oh! has three-colored hair — black, gold and pink. Aside from that, the show tends more toward weird hair styles then weird hair colors — indeed, some of the odder hair colours from Season 0 (such as Kaiba's bright radium-green hair) were recoloured to something more probable for the better known later seasons.
- Though Kaiba's green hair was an Adaption Dye Job. Whenever he shows up somewhere on the cover of the first 7 manga season 0 were loosely based on he clearly has brown hair.
Some Bleach characters have impossible hair, like Renji, who has literally red hair. Same with the Chizuru. It's also guilty of implausible hair, with Orihime and Ichigo, and it also lampshades Ichigo's orange hair. Orihime's is actually supposed to be chestnut brown, which is poorly colored on the part of the animators.
- The entire point of Ichigo's hair is that it's the color that Asian hair turns when one attempts to bleach it.
- Not to mention that Grimmjow literally has blue hair, though a somewhat uncommon shade.
- And while we're talking about arrancar, don't forget about Szayel (pink hair) or Nel (green).
- Let's not forget about Yachiru, the pink-haired terror of the 11th Division.
- Also, Hitsugaya has white hair despite his young appearance. There's also the Espada Halibel who is an example of a Dark Skinned Blond.
  - Ukitake also has white hair, although this is apparently the result of his lung disease.
- Soifon and Mayuri have dark blue hair. Yoruichi, Nemu and to some extent, Momo, have purple hair, as does Tosen in his appearances in the Soul Society Arc.
- The eerily fox-like Gin has hair which seems to change from silver, silver with lavender tint, even to full lavender with a light purple tint.
- Don't forget the Vaizards Mashiro (Green) Hachi (Pink) and Kensei (white.)
Naruto has Sakura, who has pink hair (and that being a hair-related aspect of Theme Naming), and it's apparently natural, unless she's going to the trouble of dying her eyebrows. If not for her, it would fit possibly into plausible hair due to the show not being set in Japan. (Even though everyone is culturally Japanese.) However, a recently-revealed member of Akatsuki apparently has purple hair (and the leader was revealed to have apparenly orange hair).
- Blond hair is quite common in the Naruto universe (Naruto himself, Ino, Temari, Temari's mother and uncle, and Tsunade), as are gray-haired young people (Kakashi [whose Back Story puts him in his late twenties], Kabuto).
- Many other character also have odd hair colors such as Gaara, Sasori, and Kushina Uzumaki with red; Jiraiya with White (even as a kid); Zetsu and the only-seen-on-a-manga-cover seven tailed-host with green; Kisame Hoshigaki and Konan with dark blue; Suigetsu Hozuki, Sakon and Ukon, Kimimaro Kaguya, Hidan, everyone from the Cloud Village but Yugito, (blonde), Karui (red), and the Head Ninja (black), the aforementioned Kakashi Hatake and Kabuto Yakushi, all with silver hair; and Juugo with orange hair.
  - On the cover of Volume 24, Sakon has purplish hair.
- Sasuke's hair is black but at times (especially in Part 1) his hair appears to be blue probably to fit the rest of his clothes but later on his hair is black with blueish tints on it.
- Can't forget Tayuya, who's hair is red or dark pink depending on who you ask.
- Before a certain manga cover was released, everyone assumed Karin's hair was black because of the completely solid black it was shown as in the regular pages, but it showed it was supposed to be bright red. Similarly True controller of the Six Paths of Pain, Nagato seemed to have possibly black hair in the manga, but when colored, was shown to be blood red/crimson.
  - Kishimoto has done this with again: The Mizukage looks blond (as in left uncolored) in the manga but a new cover revealed her to have Chestnut Brownish Red hair.
Mermaid Melody Pichi Pichi Pitch, where, for the mermaids at least, hair colour also indicates race. Humans and other characters can have any colour.
Tokyo Mew Mew. Technically, at least Minto and Zakuro may have stylized black hair, and the anime version of Ichigo is a more or less plausible redhead, but then there are obviously blonde Bu-ling and Ryou... Additionally, in the anime, the Mew Mews' hair colour changes from normal to outrageous when they transform, save for Zakuro and Retasu, who remain purple and green (albeit different shades). In the manga, all five girls always have fancy hair colours, transformed or not.
Galaxy Angel, Galaxy Angel Rune and Galaxy Angel Game Verse.
Magic Knight Rayearth: Hikaru's hair is red and Umi's is blue. Various other odd hair colors pop up as well, but as Cephiro isn't Japan (or anywhere else on Earth) this is Justified.
In Ai Yori Aoshi, secondary characters have realistic hair coloring, but most of the lead characters don't. Kaoru's is brown (a very non-Japanese brown), Aoi's is (appropriately) blue, Taeko's is a reddish-brown, Miyabi's is a plum color, and Mayu's is bright purple.
Corrector Yui falls somewhere in between this and implausible. In the anime, Haruna has normal roan red hair, while Yui, being blonde, puts it at least at implausible. The other Correctors have rainbow hair, but they're computer programs. In the manga, though, Haruna has unmistakably purple hair, and in the second season of the anime, purple-haired Ai comes in from the real world.
- I do, sir. I sure do. But changing the subject, in the anime, Ai's hair can pass as black in the anime, while in manga, it's dark purple (in the pilots, it's a greyish brown).
Yu Yu Hakusho's human characters have every possible natural hair color (except Genkai, who's graying now but originally had pink hair) while the more fantastic characters usually have more fantastic hair colors. Both Kurama and Kuwabara have red hair, for example, but they're very different shades.
- To be fair, however, Genkai originally was strawberry-blonde◊.
- Botan's is even lampshaded.
  Koto: Why not focus on something you're good at, Honey? Like dying your hair unnatural colors?
  - She still insists it's natural.
- Kurama's hair is black (or dark blue) in the manga.
Mahou Sensei Negima has otherwise merely Improbable hair, until you get to Misa Kakizaki, the cheerleader with purple hair, and green-haired Ninja-girl Kaede. Not sure if Chachamaru, having light green hair, counts as she's a Robot Girl. The animated adaptations, on the other hand, make it even worse, changing the hair colors of half the remaining cast.
- In the manga, Kaede has sandy blonde hair, and Ayaka Yukihiro has golden blond hair.
  - Evangeline speculates in the manga that Setsuna probably has white hair and red eyes, but dyes her hair and wears contacts. We have never actually seen this in any of the different versions of the series, though.
Samurai Seven has (mostly) plausible hair colors: browns and blacks. Then we get to redheaded Heihachi, blond Shichiroji and Kyuuzo, and Ukyo, who actually has blue hair.
Higurashino Naku Koro Ni falls victim to this. Keiichi and Tomitake's hair is brown, unusual for a full Japanese person, while Satoko, her immediate family, and Takano are all blonds (more unusual), Rena and Irie has orange hair (very unlikely for Rena considering neither of her parents do), Rika and Chie have blue hair for no adequately explored reason, and the Sonozaki family women have green hair. Naturally, no one ever comments on any of this.
- In Umineko No Naku Koro Ni Rika's Expy Bernkastel's blue hair stands out when compared to the rest of the cast introduced up to that point who had relatively reasonable hair colors, though it's justified since she is a magical being. It's blue in the visual novel sprites, but in the anime takes on a more purplish tint.
- Actually, Rena's mom has red hair too.
In Suzumiya Haruhi most characters hover around the brown-black-auburn spectrum; however, Ryoko, Emiri, Yuki, and Tsuruya have varying colors of green, blue, and grey. Tsuruya's hair colour may just be to throw us off as to her origin, since the other three are discovered to be Human Aliens before we learn Tsuruya's own secret.
- In the anime and novel color pictures, Yuki's hair is purple.
- However, nobody appears to find this strange. Could be that others do have strange hair or that their hair is actually just a visual cue for the audience to recognize these characters are not exactly normal. Perhaps in 'reality' their hair color is something normal?
Outlaw Star falls somewhere between Impossible and Plausible hair colors. Most of the characters are white, and any characters of Asian ancestry have black or dark brown hair. On the other hand we have Harry, who has blue-green hair, and Gene, whose hair is a shade of red that you're very unlikely to find in the real world.
- Harry's hair is explainable; he's a bio-android like Melfina, a genetically engineered lifeform created using DNA samples taken from a dead human. And in a setting where that sort of thing is possible, not to mention that modifications of all sorts are quite common (so much so that neither Gene nor Jim is surprised when their bounty in the first episode is a cyborg, and Jim has to look up a specific model to figure out his vulnerable spot), if not cheap, then the possibility of DNA tweaking for aesthetic purposes comes up.
Cowboy Bebop has realistic-looking characters so the vast majority of them fall under plausible hair colors... except for green-haired Spike, purple-haired Faye, and White Haired Pretty Boy Vicious. No explanation given for these unusual hair colors and nobody notices.
- As far as Spike and Faye, they're more than likely black-haired with highlights/contrast shades added in.
Almost no one has normal colored hair in Lucky Star. It's lampshaded when Miyuki (who has pink hair) explains to Konata (blue), Tsukasa and Kagami (both purple) why exposure to sunlight and seawater changes hair color. Note, however, that most, if not all, characters with funky hair colors also have that as their eye color, as such, one may pretend that their hair is perceived in their world as being black/dark brown.
- Maybe dub shuld not count, but Konata in the Kadokawa-Bandai dub says Miyuki and her mother have pink hair.
Keroro Gunsou has Natsumi's pink hair, Momoka's (and her father's) light blue hair, and Saburou's silver hair, for the human examples; the humanoid aliens seldom have "normal" hair colours. For the humans, though, this is implied to be the result of dye jobs.
Clark Kenting related example — everyone in the world of Yes! Precure 5 has some shade of brown or black hair, except for the heroines, all of whom have hair in their respective hero color even in civilian form. Red-haired Rin and (justified) blonde Urara might not stand out, but Nozomi, Komachi and Karen's pink, blue and green, coupled with the fact that the five spend a lot of time together...
- Rin's got realistic-looking brown "red" hair, which becomes bright red when she transforms. So maybe that throws people off.
Saint Seiya has a lot of characters with impossible hair color, most prominently Andromeda Shun, who has green hair color. Shun's hair was normal light brown in the manga; it was changed for the animation to make him more noticeable.
- In the manga, most of the Gold Saints had blonde hair, and the only exceptions were Dohko who kept his auburn hair from the anime, Deathmask who had silver-grey hair in the manga, Camus's was red, and Shura's was black.
The Revolutionary Girl Utena anime has Utena, and Mikage (both pink), Anthy (purple), Akio, Mamiya, and Dios (all lilac), Touga (bright red), Saionji (green), Miki, Kozue and Ruka (all blue), Juri (orange) and Shiori (wine, or perhaps raspberry). Everyone else's hair color is... possible, as most people have brown hair, some have black and some (notably and implausibly Touga's sister Nanami) are blonde.
- Miki, Kozue, and Ruka all have different shades of blue hair (Ruka himself has two!), with Kanae's mother adding in yet another. Kanae herself, on the other hand, sometimes appears to have very bright green hair. Chigusa and the unnamed main character from the Sega Saturn game have cyan and magenta hair, respectively.
- The hair color is so they'll be properly color coordinated. Besides... Ohtori Academy isn't really real anyway, so...
The Dirty Pair fall into this: Kei is a Dark Skinned Redhead with an impossible shade of red hair, and Yuri's hair (even when it's referred to as black) is usually shown as blue. However they are both genetically engineered transhumans with a questionable biology/cybernetics ratio.
Only two of the major characters in Mai-HiME have anything resembling normal hair color for a show set in Middle of Nowhere Town, Japan — Yukino (brown) and Mikoto (black, with pigtails and Eyes Of Gold). Naturally, there's also a blue-haired character in the mix, Miyu — but she's an android, so she has an excuse.
- Natsuki may also qualify as having "normal" hair — it's dark blue in the anime, but the supplemental materials describe it as being black, so she most likely simply falls under "stylized black hair."
Before the Pokémon anime changed to digital animation, James' hair was blue. Now it's lavender (the dub has made a joke about this). Jessie's hair went from fire engine red to magenta. And Tracy's was green even before the switch (just a darker shade, almost black).
- Officer Jenny's hair changed from Blue to Blue-Green.
- Come on, nurse Joy's hair is PINK! (All of them).
Full Metal Panic! is mostly realistic, but Kaname has blue hair (often described as black), and the Testarossa siblings are white-haired (often described as ash-blonde). Apparently no one finds that strange.
- All the people that seem to have issues with this in FMP are Whispereds, and all sorts of nonsense can be attributed to this.
- Of course, in Fumoffu, unnatural hair colors are given out like candy on Halloween. As you may have guessed, it's also the least serious season.
All members of the Diclonius sub-species in Elfen Lied have hair in varying shades of pink (in the anime, at least). Justified in that they are not entirely human. Also, their hair color, combined with the cat-ear-like horns on their head, single them out among crowds of humans.
- In the manga, the "third-generation" Silpelit, Mariko, has blond hair, which is completely impossible considering the fact that her parents were both Japanese and had dark hair.
Yotsuba Koiwai from the manga Yotsuba&! has green hair in colour shots. Everyone else's is normal, and absolutely no-one talks about it. (Then again, maybe they just figure she dyed it--Yotsuba isn't exactly all that normal, even for her age group.)
- The hair may be why strangers assume she's a foreigner.
  - Well, her adopted father did say he picked up overseas...
Seikai no Monshou and Seikai no Senki have an entire race of blue-haired space elves. Considering that the Abh were genetically modified to be able to live in space to the point of having been crafted a sixth sense for flying spaceships, the hair colour is really the smallest oddity...
Hair colors in Weiss Kreuz are mostly just implausible — Aya, Manx, and Schuldig (justifiable as he is meant to be a white westerner) all have bright red hair, and Yoji and Omi are blond — but some members of the supporting cast have outright impossible hair colors, such as Ouka's blue hair and, from the Oddly Named Sequel series Weiss Kreuz: Glühen, Tsuji's green hair.
In One Piece, oddly enough, the blue hair of main characters Vivi and Franky is never so much as mentioned, while longer-standing main character Zoro's green hair is ostensibly unusual enough to be cause for mockery. Maybe his detractors just hate him a lot.
Takedo, the boxer delinquent from Historys Strongest Disciple Kenichi has blue hair. On a completely unrelated note, he has the same voice actor as Franky (see above).
In Pretear, secondary characters have brown hair, except for Himeno's step-sisters, who have blueish-green and pink hair. The main cast got hair of different levels of plausibility: brown with some red mixed in (Goh), orange (Hajime), red (Himeno), blond (Shin), golden (Kei, who also has dark skin in the anime) and white (Mannen). Sasame was blond in the manga, but became white-haired in the anime (for a reason, apparently). Hayate's hair went from perfectly normal black in the manga to dark blue in the anime.
Most of the Trigun characters have realistic hair colours, but Legato has blue hair and yellow eyes to underline his weirdness, and some of the "mutant" characters have green hair among others.
Princess Tutu falls somewhere within impossible and implausible. A lot of the characters have odd hair colors (Ahiru's hair is somewhere in between pink and orange, Fakir's is a dark, dark shade of green), but Ahiru could possibly be a stylized redhead and Fakir could have stylized black hair. Mytho's hair is white, but that could be justified, given his magical origins. But then there's Ahiru's friend Pique, who has BRIGHT purple hair — so bright it's hard to think of it as stylized black hair — and Autor, whose hair seems to change between shades of blue or purple depending on the scene. And then there's Edel and Uzura's light green hair... but since they're really puppets, that might be justified as well.
- The impossible ones — though largely justifiable — not withstanding, the "implausible" hair colours in Tutu are pretty plausible, given the setting has sod all to do with Japan, by and large. Indeed, if it's set anywhere in particular, it's Germany, with a local set of characters.
  - Because we all known that Germans have green, red and purple hair. It's normal zura!
In Code Geass, the Japanese characters tend to have realistic brown or black hair, while the Brittanian characters have somewhat more outlandish hair colors and styles.
- Theres also Mao and the Chinese Federation Empress Tianzi who have gray/silverish hair.
  - Tianzi appears to be albino, complete with red eyes. Mao may be another example of albinism, as well. Possible, when you consider that whenever his eyes are shown they are always "geassed"
- Also Hot Scientist from India Rakshata Chala, who falls under the category of Dark Skinned Blond
- And of course C.C., who has green hair. Which is apparently natural.
The anime series Captain Future, based on Sci Fi novels by science fiction writer Edmond Hamilton, created in Japan in 1978 and famous in Europe during the 1980s, featured at least one main character with blue hair and blue moustache (an older male character).
Rokudo Mukuro of Katekyo Hitman Reborn actually does have blue hair, in a sort of "pineapple" hairstyle that has been made fun of extensively by the fans and the author. Chrome Dokuro, the girl Mukuro saves/ gives organs to/possesses/protects/etc. has purple hair in the same hairstyle. Semi-minor antagonist Nosaru also has purple hair. And at least three perfectly healthy, youthful characters have white hair (and one has gray).
Minami Juuji of Nabari no Ou has inexplicable green-blue hair. Raikou's pink 'do is okay, since he obviously dyes it (though he, his sister, his mother, and Yukimi Kazuhiko and Kazuho are all natural Japanese blondes). Aizawa Kouichi and Kuro'okano Shijima both have pure white hair, but this is because they're both immortal beings; a human fusion with a snowy owl and white cat, respectively.
Tengen Toppa Gurren Lagann is rife with examples of Anime Hair, since it's basically an over-the-top, hot-blooded middle finger to science. Heroes Simon and Kamina both have blue hair (though Simon's looks kinda black), Yoko has brick red hair (as does Gimmy), Leeron's is aqua, Darry's is cotton-candy pink, Kittan's is blond and black, and Nia... just. Nia. Nia.
Many of Gintama's cast members all have reasonably realistic hair colors, but Gintoki's silver hair (which somehow appears light blue) sticks out like a sore thumb; this is actually pointed out within the series itself. Then there's Sacchan and Otsuu's purple hair, and Kagura's bright red-orange 'do (though this may be slightly justified, in that she's not human.)
GaoGaiGar is somewhat... inconsistent about this. A hair color is normal, or at least unworthy of comment, if it does not come from alien heritage. (Hyuuma could actually have green hair, but it's almost certainly dyed, if so. And Akane probably actually has black hair.) But, Kaidou with red hair apparently looks much stranger than Kaidou with mauve hair. And Kaidou with mauve hair and Hana with pink hair are just as plausible as nearly everybody else's normal hair.
Max Jenius from Super Dimension Fortress Macross. Or Mylene Jenius (blue+green=pink? Who knew?). And Macross Frontier gives us Ranka Lee, with her green hair.
- In Robotech, Max Sterling's blue hair is dyed.
- In the case of Ranka and Mylene, this is probably justified, as it seems to be the case that odd hair colors are a natural Zentradi trait, and both of them have partial Zentradi ancestry; in fact, Ranka has inherited a rare Zentradi trait of naturally empathetic hair, so imagining that green is her natural hair color is hardly a stretch. Milia from the original Macross (Mylene's mother) and Clan Clang from Macross Frontier, both fully Zentradi, have green and blue hair, respectively. The odd ones are Alto, Nanase, and Grace from Macross Frontier; the latter's hair is blue, and the former two have purple hair. Zentradi ancestry seems fairly unlikely in all three cases.
In The Law of Ueki, the title character has green hair, a likely reference to his power to turn trash into trees. The female lead, Mori Ai, also has aquamarine-colored hair.
In a cast consisting of characters that mostly have "normal" hair color, Death Note's Near happens to have stark white hair, while Matt sports unnaturally green hair, at least in the anime adaptation and TCG (in the DS game adaptation, it became blue). Some images of L and Teru Mikami also have their jet-black hair mutated to more of a deep black-green, and the very first colored manga image featuring Mello depicted him with hair just as white as Near's.
Jun in the original Science Ninja Team Gatchaman had deep green hair that occasionally appeared black or brown in episodes, to the point where fans theorized that her hair was meant to be so black it only SEEMED "green". The sequel series and artbook images threw this into doubt though, when her hair became a more obvious, brighter shade of green.
Many characters in Strawberry Panic have blue hair, as Shizuma complains in this fanvid. Shizuma herself has silver hair; Nagisa's is bright red, Chiyo's is blue-green, Hikari's is very light blonde, and Tsubomi's is pink. In fact, the only major characters with reasonable colours are the raven-haired Yaya and Chikaru.
No two Sibyllae in Simoun have exactly the same hair colour (including the two who are sisters). Among them, they've got the whole spectrum covered.
Normal hair colors are almost unheard of in Mahoraba, unless your male, that is.
For the most part, Rah Xephon almost entirely plausible hair colors. Almost. While Makoto's hair is explained as Albinism, there's still Quon's purple and Ayato's silver/gray hair to get past. Then again, neither of them are exactly human...
The girls in the Tenchi Muyo! series all have odd hair colors except for Mihoshi, who is blonde. Ryoko has what appears to be a very light shade of teal hair, Washū has pink hair, Ayeka has dark purple hair, Sasami has a teal-blue shade of hair with it's brightness depending on the series(sometimes it looks like light blue-green and sometimes it looks a bit sky blue), Kiyone has dark green hair, though it can look black at times.
- They're all aliens anyway, though.
- Washū also has red hair, not pink, so she goes under barely normal in that area. Of course, Mihoshi is a brown-skinned blonde, and Washū is an [[lolicon age-bender]]...
- Subversion of the escape clause: Aeka's purple hair is revealed in the manga to be dyed... it's actually the same light blue as her sister and mother.
  - Why is an alien bluenette dying her hair purple, you ask? To match her second mother's [Jurai royals practice polygamy] naturally purple hair! Please note that said second mother is a full-blooded human from 13th century Japan, a fact which takes the escape clause, rips it into small bits, incinerates the bits with a flamethrower, and then urinates on the ashes.
  - Allegedly it was about tweaking her available genetics to resemble second mother Funaho (who has black hair) as much as possible, hence her father's purple-hair DNA traits were turned more dominant.
Mononoke features two blond-haired, blue-eyed characters in feudal Japan. If they actually were white, they'd be dead in a minute.
Ayanami Rei is often called an albino by fans, but instead of white/colorless hair and pink eyes, she has pale blue hair and red eyes.
- Subverted by the fact that she is part Angel. Justified in episode 24 by fellow [1] Kaworu Nagisa, who has gray hair (nigh impossible for a 14-year-old, bar a dye job) and red eyes.
- More than likely Hair Color Dissonance on behalf of both characters.
Mikoto and Nara on School Rumble both have blue hair. Tenma appears to have purple hair.
Arale in Dr. Slump gets away with this because she's an android.
In at least the second series of the Ranma ½ anime, Akane is portrayed with light, rather washed out blue hair. In all other seasons, though, her hair is portrayed as either black or black with navy highlights. Shampoo, on the other hand, is a much better fit for this trope with a long mane of deep blue hair (although in some episodes, mainly the OA Vs, her hair is more purple than blue). An anime-only episode reveals that, when she was eighteen, her great-grandmother Cologne had dark blue hair.
- Anime Shampoo's exact hair color (blue vs. purple) spurred a vicious debate among fans at one point on message boards.
I'm surprised Psyren hasn't been mentioned yet. While in black & white the hair colors seem normal enough, but for the ocasional colored section...
Tamahome and Chichiri from Fushigi Yuugi have blue hair of different shades (but the former's hair is often mistaken for green), while Nuriko, his deceased little sister Kourin, and Empress Houki have purple hair. Chiriko's hair is a cross between brown and pink and the Nyan-Nyans have bubblegum blue hair. Tokaki, Subaru and Tenkou have silver hair (this holds true for the former two even in youth), and Renhou and Miiru have silver-purple hair. Soi's hair is a shade of maroon, while Nakago is the only one who has blonde hair in the book world, and this is actually significant. The human forms of all the Beast Deities have hair in the color by which they are identified.
The Harukanaru Toki no Naka de franchise is fond of this. Normally, if a character is blond (and has blue eyes), you can tell that said character is really blond and blue-eyed, which indicates that he either belongs to the Oni Clan if he is from Kyou, or is not entirely of Japanese origin. The fact that the rest of the central cast makes up a nice rainbow when standing together (the anime adaptations enjoy pushing the hair/eye colors Beyond The Impossible) doesn't bother anyone, and even if you ignore certain characters who aren't quite human, it won't help anyway.
In ARIA, most everyone has normal colored hair, except for some of the main characters - not unexpected, since this is partly a fantasy series. Akari's hair is pink, Aika's is bright blue, Alice has green hair, and Athena's hair is lavender.
Wedding Peach has quite a few, including the titular heroine.
In Please Twins this trope is even more jarring than normal - the three lead characters, two of which are siblings have red, green and purple hair. This is never mentioned, but thier unusual (green) eye colour is several times.
In Fairy Tail the main hero, Natsu, has pink hair. One of his companions Erza is a red-head (Not orange-red. Cherry red). Erza's antaganist character (since every character has one big bad affiliated with them) Gerard has blue hair.
Crystal from Pokémon Special inverts this trope. She originally had brown hair, but was changed to blue to match her game and anime counterparts. She changed back to brown recently though, which makes people wonder what will happen in the Heartgold/Soulsilver arc..
Diebuster has this in the form of protagonist Nono, whose hair starts out pink and turns into a glowing psychedelic swirl when she regains her memories and recombines with the solar system's dormant defense robot network. Given that this series is from GAINAX, makers of such refined weirdness as Abenobashi Mahou Shoutengai and FLCL, this is probably unsurprising.
Sieg Hart, Hardner and (debatebly) Belnika are the three blue haired examples of Rave Master. In addition, Haru, Gale Glory, and Let have silver hair. Ex-love interest Reina's hair is green, Nagisa's is pink, and in the most normal case, Shuda's is cherry red.
Tazusa from Ginban Kaleidoscope has purple hair, her best friend's is green, and her rival's is dark red. Pete's dirty blonde hair is justified since he's Canadian.
The main cast of La Corda d'Oro contains a rainbow of unnatural hair colors. Let's see... Kahoko Hino's bright red, Len Tsukimori's blue, Ryoutarou Tsuchiura and Kazuki Hihara's varying shades of green, Azuma Yunoki's purple, Shoko Fuyuumi's bluish-green, Kanazawa-sensei's reddish purple, Shinobu Ousaki's other shade of red, and Keiichi Shimizu's blonde. Lili is a subversion, since he's a fairy and it seems that he came with Seisou Academy's founder from Europe anyway.
Subverted because they're aliens, but the non-Earthlings from Magical Girl Lyrical Nanoha have some pretty wild hair colors, such as Signum and Caro's pink and the Nakajima family's blue. (Then again, you have to question how nobody picked up on the little girl in the wheel chair wandering around with a bunch of rainbow-haired foreigners in A's.) On the other hand, Nanoha's friend Suzuka is pure-blooded Japanese, and her entire family has purple hair. (Interestingly, that includes the maids, who aren't related to them as far as I know.) Nanoha's friend Alisa's blonde hair is an aversion, though — she's not Japanese.
Rowan/Touma of Ronin Warriors has blue hair, which is unusual since this series tends to avoid giving the main cast odd hair colors. The 4 warlords however have brown, white, green, and blue hair.
In GA Geijutsuka Art Design Class, while some characters have acceptable hair colours—Professor is black and Kisaragi is deep brown), Tomokane is green, Nodamiki is pinkish-blond, and Namiko is a light brown. Lampshaded in one strip wondering why Western Animation uses Amazing Techicolor Population and anime uses this. It should also be noted that these are the characters' in-universe hair colours; Namiko and Nodamiki had to submit their child photos to the school to prove they had not dyed their hair.

Lots of examples in Marvel comics. From X-Men we have Polaris who has green hair as part of her mutation. Her father Magneto and half-brother Quicksilver both have silver hair. Storm inherited white hair as the latest in a long line of mystical African shaman priestesses. Rogue has a white streak in her auburn hair which is natural (though, in the movie continuity, it's a side effect of having the power drained from her to power Magneto's mutation machine at the end of the first movie). Nate Grey also had white forelocks. Psylocke originally dyed her hair purple, but after her genes were scrambled by the villainess Spiral, the color seems to be permanent. Phyla-Vell (Quasar) and her brother Genis-Vell (Captain Marvel) both have white hair as part of their Kree heritage.
- Less natural is the way that Rogue's white streak changes size and location depending on who's drawing her at the time, from two streaks at her temples to a massive skunk-stripe covering the entire crown of her head to, currently, just her bangs.
  - The reasoning for the first change was that apparently Walt Simonson or Paul Smith suggested that her hair have one central streak rather than two streaks near her temples, as the latter made her look too much like a middle-aged woman as opposed to the 16-year-old she was. After that, your guess is as good as anyone else's.
- During Claremont's first run on the title, Rogue's hair was mentioned as being dyed at least once. Whether this is still true is anyone's guess.
Deliah Blue from the Star Wars: Legacy comics has blue hair, hence the name. This is unusual for her species (Zeltron), who are usually red-haired.
The Joker from Batman has neon green hair caused by the chemicals he fell into. Probably.
For decades, Superman's black hair was always colored with blue highlights. This led many fans to joke over the years that Clark Kent's friends really ought to have noticed his hair was blue. In fairness, Lois Lane's black hair was shaded the same way.
- Lyla, Kal-El's alternate universe wife in Superman: Godfall, had purple hair.
The "Howard & Nester" comic in Nintendo Power had a Japanese artist for most of its run, which led to a few manga influences sneaking in. One of them occurred in Issue 3, with Nester showing off to a pair of children, one of whom was a blue-haired boy.
The main character of Blue Monday, Bleu L. Finnegan, has blue hair. In case you can't tell, this is heavily lampshaded.

Most of the characters in Sky Blue have fairly sensible hair, but Jay has unnatural red hair, Cade's is white, and Maya's is green. Zed has mauve hair, but since he's a punk with a long tube of hair extending from the top of his head, it's likely to be dyed.

Leeloo from The Fifth Element has neon orange hair.
- She does? I hadn't noticed...

In the fantasy novel Drink Down the Moon by Charles De Lint, one of the faerie women living among humans who is posing as a young punk musician has natural pink hair. Of course, anyone who sees her (anyone who sees her and due to her glamour is led to think she is human, that is) assumes it's dyed.
In Jacqueline Carey's Kushiel's Dart, Alcuin's hair is literally white even as a young child. This is implied to make him unearthly beautiful.
Members of House Targaryen in A Song of Ice and Fire have platinum-colored hair.
The novel Super Folks, one of the earliest deconstructions of the super hero genre, has a Super Man Expy named Indigo as its main character. Since comic books always shaded Superman's black hair with blue highlights, Indigo actually does have blue hair. Thankfully, none of his Secret Identity's friends ever seem to notice.
How could someone forget the examples in The Twelve Kingdoms novels? The starting setting is a plausible, normal Japan, where people have the Japanese hair colors and such. Then, the main character, Youko Nakajima, has an almost literally red hair, and it's completely natural (although people accuse her of dying it red to bring attention to herself). Then, a platinum blond (almost white-haired) Japanese looking guy appears from nowhere and wants to take Youko to his world (making people assume he's a gangster, and she's secretly his girlfriend). When she finally goes to this world, between all the suffering, she sees Japanese-looking people of all skintones and hair colors. All colors in the rainbow, literally. The anime shows it with beautiful detail, but not as much impressive as it's the novel description. But taking in consideration they are sorta like aliens...
An actual, legally enforced law in Crest of the Stars. The Abh were created by genetic engineering and were all given blue hair as part of the process and they kept that when they became independent. The anime shows them as a fairly uniform colour with only a handful of exceptions but the novels describe them as running gamut from very pale blues and blue-greens to dark blues and purples.
The people living in the Capitol in The Hunger Games are described as having not just weird-colored hair, but also dyed skin.
Subverted in Isaac Asimov's story My son, the physicist, where an elderly woman has hair dyed apple green, which is extremely old fashioned - modern girls, apparently, have rainbows on their heads.

The live-action Sailor Moon television adaptation reserves the weird hair colors for the girls' heroic forms. One exception to this is Sailor Luna, whose hair is blue even when she is not transformed. Nobody seems to notice this. (Interestingly, many fans consider Luna's live-action human form to be a replacement for Chibi-Usa, so keeping her odd hair color may be intentional.)
The female astronauts in the series UFO always wore purple wigs. Also, skintight spacesuits.

Music example: 2D and Noodle of Gorillaz both have blue hair, and it's been proven that it's natural for both.
- Noodle having blue hair applies more to phase one in a way. Later through the years, Noodle's hair is more purple than anything.

The Kat went through a period where she wore very unusual outfits, many of which involved dying her hair unusual colors. One of them was blue, another was a scarlet red.
Independent circuit female wrestler LuFisto models her outfits on anime characters. She sometimes dies her hair pink, and at least once, yeah, blue.

In Dungeons & Dragons, the moon elves of Faerun commonly have white, silver or bright blue hair and blue-tinted skin, while the gold elves (also called sun elves) may have metallic golden hair and golden eye color. Not to mention the bizarre hair, eye and skin colors of half-dragons and dragonblooded characters who are descended from dragons Color Coded For Your Convenience (red, green, blue, black, white), or of various planar nonhuman races like the Genasi who are the offspring of elementals and humanoids.
- To be fair, Dungeons & Dragons is a fantasy setting, and most of these listed races are just that: different races. IE, not even (entirely) human in the first place.
In the GURPS Discworld scenario "A Little Job For The Patrician", published in Pyramid Magazine, the heavily anime-based villain insists his trolls all grow different coloured moss on their heads, so he can tell them apart, and his Igor has implanted blue hair, just because.
In the heavily anime-influenced RPG Mekton, Mike Pondsmith's infamous Lifepath character generation system includes a table for hair color, which includes both more staid, real-life hair colors as well as anime hair colors such as green, purple, pink and, yes, blue.
This is fairly common in Exalted. People from the West often have blue, green, or purple hair, people in the East have green hair, Southerners have red hair (not red hair as in what our world calls orange hair, RED hair)... and that's not even going into the colors people get when they're exposed to magic. Wyld mutations can theoretically leave someone with hair any color of the rainbow (or, for that matter, with rainbow hair), Abyssal Exalted are often White Haired Pretty Boys (or Girls)...the list goes on.

Everyone except Chaud (with two-tones white hair and black sides) in Mega Man Battle Network has natural hair colours and reasonable hair styles.
- Excuse me? Meiru has purple hair, and Dekao has a fin on his head. Madoi has outrageous bright pink (with a giant poofy style, even), Shuuko has a pleasant shade of indigo, and Laika has light aqua-green hair. Shall I go on?
- Don't forget Battle Network's sequel series, Star Force! Insane hair styles, and Sonia's hair style is PURPLE! Not to mention Pat's hair being green due to the Theme Naming.
  - Picking on Misora's relatively normal (color notwithstanding) hair when Twin-Drill Luna◊-iinchou is right over there?
  - The third game gives us Eos and Queen, who have matching shades of actual blue hair, and Heartless, who sports a pink 'do.
- And Mega Man ZX is an even worse offender. Grey has... Grey hair. Ashe has blue hair. Other main characters have strange hair colours and styles... The strangest of them all has to be Prometheus and Pandora. Prometheus' hair is blue, and Pandora's hair is green, and they look like capes until you notice the one scene in Advent where they don't have their helmets on. But Prometheus can kill people with his hair. What Do You Mean Its Not Awesome?
  - Well, somewhat justified with Grey, Prometheus and Pandora, as they're not humans.
  - And Ashe is only part human, as everyone in ZX who isn't explicitly a reploid is a cyborg. Pure humans have apparently gone extinct by this point.
  - Are you forgetting Albert himself? He actually has two hair colors in a different way than other people. He has teal hair in his Sage Trinity body, but his "real body" has freaking magenta.
- ZX aside, the main Megaman universe is actually pretty sensible abbout this. The original Megaman did have blue hair at one point, but he usually switches between black & brown. The only character with an unnatural hair colour in the X series is Marino, with seafoam green. The Zero series doesn't even have one exception. In Legends, we have the purple haired Megaman Juno who is obviously inhuman & the mysterious Yuna & Sera & their servants, synthetic lifeforms of indeterminate type whose humanoid forms resemble black women with light green hair.
  - Excuse me? You've must not have played a lot of the X series or just didn't pay attention (considering you mentioned Marino). Let's go down the list of who you missed.
  - From Command Missions we have Nana who has pink hair with a single white bang; and Scarface who personifies this trope with light-blue spiky long hair. Dynamo from X5 and X6 who personifies this trope with an aqua blue hair. Lumine from X8 who has purple hair that is styled in a mix between whatever Tron from Legends has going on plus an emo hair fringe, and also from X8 is Layer with purple hair, AND Pallete who has blonde hair with pink stripes in an...unexplainable style◊. Axl from X7 and X8 has pretty normal hair normally but when he uses his "white mode" it turns purple. And speaking of other modes is any of Zero's other forms who have a lighter shade of blonde to them.
  - Justified since they're all reploids.
The works of Key Visual Arts would fall under "improbable", but there is always a small amount of characters with odd colours: Nayuki and Akiko (purple), Kano and Michiru (blue and magenta), Kotomi (blue), etc.
Advance Wars: Days of Ruin has, despite its generally more realistic tone, a blue-haired and several teal-haired characters. A redhead too, but at least that's a possible color in real life, if rare. Most characters stay in the realistic range though, but it's still a third of the playable cast.
- It should be noted that all of these characters are "clones" of the same character, however that works. (We're talking multiple genders here, people.) Not that that really explains anything, but still...
Fire Emblem has lots and lots of strange hair colours to the point that the fact that Leaf (the main character in Thracia 776) has brown hair is noteworthy, this is somewhat lampshaded in the Path of Radiance and Radiant Dawn, where Ike and Michiah are always identified by there hair colour (Blue and Silver respectively, Michiah even has the title "Silver Haired Maiden").
- In fact, Fire Emblem characters can often tell their own families by hair color. In The Sword of Seal, red-haired Roy and blue-haired Lilina inherited the hair colors of their respective fathers (Eliwood and Hector), Nils and Ninian from The Sword of Flame have the same pale green, and the main twins from The Sacred Stones both share a light teal with their father. Examples of characters sharing colors with their parents and siblings go on like this for a while. Makes you wonder why Tana from the The Sacred Stones doesn't have the washed-out grey of her father and brother.
  - Obviously she must take after her mother, who we never see.
- Truth be told, the Fire Emblem series tend to alternate between having a traditional blue-haired protagonist in one game and one with a different hair color in the next. Marth (from Shadow Dragon and Mystery of the Emblem), Sigurd and Celice (from Genealogy of Holy War), Hector (from The Sword of Flame), and Ike (from Path of Radiance) all have blue hair, while Alm and Celica (from Gaiden), Roy (from The Sword of Seal), Lyn and Eliwood (from The Sword of Flame), Erika and Ephraim (from The Sacred Stones), and Micaiah (from Radiant Dawn) are all exceptions.
Subverted with a deadpan kind of hilarity in Digital Devil Saga: the girl who fell from the sky is instantly recognizable and keeps the characters in a kind of awe with her bizarre black hair and brown eyes. Fluorescent-red-haired Heat, purple-haired Argilla, and green-haired Gale simply can't understand how a human could have such strange hair colour.
Tales Of Symphonia looks to avert this for 2/3 of the first disk, with humans having only realistic hair shades, and only Elfs (and Half-Elfs) have strange hair colors (such as teal), but then you go a parallel world and find people with lots of strange hair colors such as blue and pink.
- In Tales Of Symphonia Dawn Of The New World, there is a skit where Tenebrae is offended by Genis's comment on his age, and Tenbrae reminds him that he has a full head of white hair. Genis responds with: "It's SILVER!!!"
- Tales of games tend not to bother, really. Highlights of the series include Meredy's lavender (Eternia), several types of bright pink (Arche from Phantasia, Chelsea from Destiny, Presea from Symphonia, Hermana from Innocence), and a smattering of blues and greens for good measure.
- Hearts averts this (Mechanoids and aliens excluded), to the point where the Mysterious Waif and Big Bad are explicitly identified by hair color; myths describe an "emerald-haired princess" and a "devil of blood-red hair". Well, mostly. The Quirky Miniboss Squad has hot pink and teal.
Despite the fact that the Phoenix Wright Ace Attorney series takes place in a fairly realistic universe, no one seems to feel the need to comment on the hair colors of Franziska, April, Redd, or Lisa Basil (metallic blue, pink, purple, and electric blue, respectively). While Redd and April arguably could've dyed theirs, and Lisa's could just be part of her gimmick, Franziska's hair really has no explanation. And that's not even getting into some hair styles that seem to completely defy the laws of physics...
A large majority of Disgaea characters, demon or not, have absurd hair colors ranging from blue to white to neon pink.
While Link's hair has historically fluctuated between red, brown and blond in his various appearances, his hair was inexplicably pink in A Link to the Past.
- This was just the sprites, however. In the associated art for the game, Link's hair was a light brown.
- It also justifies why Link becomes a pink-furred rabbit in the Dark World.
- In the Ocarina of time, Links childhood friend, Saria, has vibrant green hair. She's the forest sage as well, which may explain her unique hair colour in relation to the usually brown haired kokiri.
- Speaking of Saria, In Twilight Princess Ilia has blonde hair with a greenish tinge. This is likely intentional, since Twilight Princess features several characters who are counterparts of Ocarina of Time's Sages. (Rauru=Auru, Impa=Impaz, Ruto=Rutela/Ralis, Darunia=Darbus).
- The teenager who runs Bombchu Bowling Alley in Ocarina of Time and the Treasure Chest shop in Majora's Mask has neon blue hair, and wears a hot pink shirt. Ironic in Ocarina of Time, where she runs a buisness based on big moving neon targets.
- Nayru's air is blue, while Din's hair is fiery red and the third Oracle, Farore, feature the same shade of green as Saria. Kafei's got purple hair, while Midna's hair is literally the colour of fire (No, not just red). Also, considering her age certainly bleached it quite a bit, Anjean seems to have had purple hair, like Kafei, at one point. Finally, the fairies in the first few games were always portrayed with pink hair in the artwork.
Falling somewhere between all examples is Ritz from Final Fantasy Tactics Advance, a girl who has crimson hair, even in the "real" world. It's a dye-job, as her hair appears to be albino (pale lavender) despite the rest of her, plausibly-under-the-circumstances a deadened shade of the deep red she dyes it.
In Elite Beat Agents, Agent Foxx has silver hair. Meanwhile, Cap White has pink hair... and she's a white blood cell. Also, Morris seems to have purple hair, Derek has red hair, and J's is orange. Don't get me started on J's hair ''style''...
Humans in the freeware (and soon to be WiiWare) game Cave Story tend to have dark green hair (of the few we see, anyway). Supposedly, this is because the game's creator found that black hair wouldn't stand out enough against the caves' dark backgrounds. There's also Misery, who has blue hair (or green, depending on whether you're looking at her in-game sprite or her character portrait...).
The Servants in Fate Stay Night don't count, but a couple of the humans have strange hair too — most obviously the Matou siblings, Sakura (purple) and Shinji (blue). You don't want to know how Sakura ended up that way...
- Sakura is actually a subversion, because purple is not her natural hair colour, and the reason behind this is big part of the plot of the Heaven's Feel route of the game.
Ciel in Tsukihime.
- Ciel has bluish black hair, predominantly black if you look carefully. In text, meaning according to the author, she has black hair. Dunno what color her dad had but her hair color is probably evident to the fact that her mom was Asian.
Persona 3's blue-haired Main Character. Complete with peek a bangs. His hair is one of the many things that makes him unbelievably sexy.
- Not to mention his look-a-like in Devil Survivor sports the same blue hair.
- All of the major characters in the Japanese version of the original Persona had normal hair colors — Ayase was explicitly stated to dye hers, and Brown is supposed to have brown hair, like he appears to everywhere but his in-game character portrait — but Maki (Mary) was given pink/primary-color-red hair in the US version because they thought it would make it seem less Japanese. Did we mention that Atlus USA's translators at the time were a load of brainless idiots? They were fired and badly beaten as a result. Several died from their injuries. Then, they were ground into a fine powder.
There are lots of odd haircolors in the Lunar games, but an NPC in the first town in Silver Star Story calls Luna 'The pretty blue-haired lady', so apparently blue hair isn't that uncommon.
Phantasy Star of course.
Super Robot Wars franchise original characters. There's a fair amount of brown or blond haired characters, but just point at random and 7 out of 10 times it will be someone with an unnatural hair color.
Optional for The Sims 3. You can now give your sim exotic colors, with exotic highlights. Give them a head full of rainbow if you like.
Kingdom Hearts isn't immune to this. We have White Haired Pretty Boys (Riku, all of Xenahort's variations, and while not relevant to the plot, Sephiroth). Zexion, Saix, and Aqua all have blue hair. And last but not least, let's not forget Marluxia. He has pink hair, for god's sake!
- Don't forget Axel's red hair. Not realistic red. Blood red. And another one for the ladies: Kairi's hair is also a thoroughly impossible shade of red - although that one, at least, looks like it could be achieved with a dye.
The Gria race from Final Fantasy Tactics A 2 have four assortments of hair colors, depending on the class. For the allies, red for Ravagers, blue for Hunters, green for Raptors, and purple for Geomancers.
Every. Single. Final. Fantasy. game. Sure, some of them aren't human—but then, others of them are, and plenty of the other nonhumans have perfectly normal hair colors.
- The graphics of the original game don't allow for much in the way of zaniness (with the exception of the Red Mage's white hair and, in early versions, the Thief's blue hair), but Amano's original artwork and FM Vs in the later remakes of the game have the Warrior/Knight character with silver/white/grey hair.
- From Final Fantasy II, there's Firion, with white hair as a young man, Maria and her indigo hair, Leon and his blue hair, and Leila with either blue or violet hair.
- Luneth in the DS remake of Final Fantasy III has silver-gray hair despite being a teenager.
- Cecil and Edge from Final Fantasy IV have either white, silver or purple hair, Depending On The Artist. Rydia has green hair.
  - Ceodore in Final Fantasy IV: The After Years, despite having parents whose hair is either white, silver or purple (Cecil) and either very blonde or brown (Rosa).
- In Final Fantasy V, Lenna has pink hair, and Faris has purple hair... at least, according to the sprites. Artwork depicts them both as blondes.
- Terra from Final Fantasy VI has either green or blonde hair, depending on whether you believe the sprites or artwork. Dissidia splits the difference by giving her blonde hair in the main costume and green hair in her alternate costume. Setzer's also got a headful of white/silver hair, due to (possibly) being albino.
- Final Fantasy VII has the iconic Sephiroth and his just-as-iconic long silvery hair.
- Ultimecia in Final Fantasy VIII also has that long white/silver hair.
- Final Fantasy IX gives us yet another silver-haired individual, Kuja, as well as the blue-haired Eiko. Trance Zidane also has pink hair.
- Then there is Seymour, one of the villains of Final Fantasy X , who has blue hair on account of being non-human. However, the perfectly-human Yunalesca also has...long silvery-white hair (are you noticing a trend here?)
- In Final Fantasy XII, all Viera are born with white hair, though according to the manual some of them dye it human colors. Inversion?
- In Final Fantasy XIII, Lightning and Serah both have pink hair. Hope has the ever popular silver hair..
- Selkies, an entire race in the Crystal Chronicles series, have this as one of their defining feature. The only "normal" hair color among them is red.
Keira in the Jak and Daxter series has green and blue hair.
A number of characters in the Pokemon games have oddly colored hair. Steven for example has white-silver hair, despite him seemingly being in his early 20s. Brendan also appears to have black and white hair, though that's very much debatable.
- There's also Kris, Dawn, and Lucas, all of whom appear to have blueish hair (light blue for Kris, dark for Dawn and Lucas).
The cast of the Touhou series of games can be handwaved as Improbable since most of them aren't human, but with a few exceptions:
- Sanae Kochiya, a human who, until recently lived in the outside world, has green hair.
- Marisa Kirisame, despite being a full blood Japanese, has blonde hair (or red in the first game).
- Sakuya Izayoi has white/silver hair. Also Fujiwara No Mokou has this hair colour as well, as do Keine and Rinnosuke, however those are half beasts.
Somewhat averted in Katawa Shoujo, where most characters have perfectly ordinary brown, blonde or red hair, and Misha's bright pink is immediately noticed as unusual. However, the hair color spectrum is still a bit too wide for a Japanese school, and some of the darker-haired characters have natural blue or purple highlights.
In Fallout 3 you can create your character to have vastly unnatural hair colours, and all the Raiders have unnatural hair colours. One character says of her daughter 'has dyed orange hair' so it's accepted as dye-jobs but... where on earth are they getting the dye in a post apocalyptic wasteland?
- People dyed their hair long before the modern era...
Many characters have blue/green/pink hair in the later games in the Backyard Sports series.
As a general rule, most examples of this in the Breath of Fire series fit as Plausible Examples—the one that does not would be that of Ryu 1/8192 in Dragon Quarter as he starts out as a normal, actually fairly low-caste human with dark blue hair. (And yes, Word Of God explicitly states this Ryu was meant to be a normal human.)
Mitadake High, being a game which gloriously bases itself on all manners of Animé stereotypes, lampshades this by having the aliases of most of the characters being their hair colour (such as "The Blue Haired Boy" or "The Long Pink Haired Girl"). In fact, the only two that aren't are "The Boy With Goggles" and "The Boy with Sunglasses" (which are other stereotypes anyway). The hair colours are: Blue, Red, Green, Orange, Purple, Brown, Black, Silver, Grey, White and Blonde.
Grandia provides a full palette: hero Justin has vibrant red hair; childhood friend Sue's is purple; Action Girl Feena sports green while her sister Leen's is blue; Quirky Miniboss Squad Nana, Saki and Mio are purple, red and green respectively; ethereal Staff Chick Liete has purple.
Yo-Jin-Bo has Muneshige, Bo, Kasumimaru, and even one of the unnamed ninja with blue hair. Yo's aqua hair could also count.

Homestar Runner spoofs this when a fan named James asks what Strong Bad would look like as an anime character. Strong Bad decides that he'd be shiny, he'd have huge green eyes, he'd have cooler boots, and blue hair, for some reason. Humourously, on one main page, scrolling over "Store" gives 1-Up (Homestar Runner's anime counterpart) blue hair.

Zoe from Sluggy Freelance is shown as having blue hair. Since no mention has been made of her mother berating her for dying her hair, we must assume that's her natural color. (Though in an Alternate Universe, she has purple hair.) This is possibly the result of Pete Abrams's computer monitor not being properly calibrated during the early days of the strip; the same problem also caused Zoe's skin tone to be lighter than intended, forcing Pete to scrap his plans for making her half-Cuban.
- Zoe is more a case of Hair Color Dissonance: her hair is black but is shown as blue-black, like Superman. Her mother has this too. However, the cannibal "Freaky" Fred has obviously green hair, and this is never explained.
While most of the Girl Genius characters have perfectly normal hair colors, one character, Zeetha, has green hair. This is remarked upon, and presumably is less weird in the Lost Kingdom she comes from.
- Don't forget the Jagers, whose hair ranges from green to purple. Justified because they aren't human.
In El Goonish Shive, Tedd's father has blue hair, Tedd himself has purple hair, and a goth girl has green hair. Several characters were surprised to learn that Susan's dark blue hair was a dye job. There have also been various background characters with green, blue, or purple hair. Dan stated that all hair colors except Susan's are natural.
In Gunnerkrigg Court, some of the Suicide Fairies gain natural hair colors when they become human, while some of them keep their original colors, like green or purple. They all have gray eyes.
- Also, Antimony and her mother have pink hair. Considering how one kid calls Annie "carrot top", it's very likely that this is actually red hair represented as pink, much like how black hair is sometimes rendered as a dark shade of blue or purple.
- Marcia Sutton has green hair. This, along with the fact that trees are Serious Business for her, is explained by the fact that she is a actually dryad, revealed shortly after her introduction.
In The Order of the Stick webcomic, blue hair (both light and dark) is common in characters from the Japan-inspired and aptly named Azure City. Purple or teal hair is also possible.
- This seems to be common with elves. Vaarsuvius has purple hair, Inkyrius has light green hair, their children have teal and orange hair respectively, and Aarindarius has pink hair.
In Schlock Mercenary, Keenspot co-CEO Darren "Gav" Bleuel dyes his hair bright blue. No, really. I mean, seriously bright.
- Fairly early in the strip, but spoiler tagged just in case, Gav is perfectly cloned, including his hair and memories, 950 million times, making blue the single most common hair colour in the galaxy in the space of a second.
In The Law Of Purple, blue hair, along with black, brown, blond, and red hair, is a natural hair color for humans. Any other strange color means either that it's a dye job or that the person isn't human.
In The Dragon Doctors, Sarin the wizard has green hair and Kili's hair is bleach-white. This is explained as extraordinary circumstances, though, both resulting from different experiences they had with magic.
The common humans (and the Seraphim and Goddesses) all have this in Fetch Quest: Saga of the Twelve Artifacts. So far, only Nephilim Lachesis had dyed her hair, and it was all because she didn't want to look too much like her less refined twin sister Saffron. However, the Tangashen completely avert this.
In Aetheria Epics, normal hair colors for people in Veil include pink, purple, and green. Having black hair can give you away as an outsider.
Last Res0rt has plenty of justification for odd hair colors (what with all those aliens), but White Noise's hair has actually aged into a pale blue. His original hair color appears to've been dark grey with blonde streaks in it. (or was it blonde with dark grey streaks?)
Karcharoth of Cry Havoc has purple hair. Its unknown if this is natural, dyed, or the side effect of something he has done/been exposed to

Rhine from Open Blue has "cherry blonde" hair (actually named in-universe after sakura flowers), the result of a rare genetic condition of some sort (it's the 18th century, so nobody has really studied it that much), that basically gives it to literally one in a million people. Captain Zuru, being an expy of Kamina, has blue hair.

Taken to an extreme with Doug which not only has a rainbow of hair colors, but skin colors as well. Doug's best friend Patty is a Dark Skinned Blond, and his other best friend Skeeter has blue skin.
Ignoring the yellow skin, the characters of The Simpsons include some naturally blue-haired characters such as Marge and Milhouse's family. There are even some purple-haired people such as Patti and Selma.
- There's also characters with green hair (Krusty, Sideshow Mel) and maroon hair (Sideshow Bob).
- Marge may have been naturally blue-haired in her younger years, but everyone knows that these days she dyes it with Blue #52 (or is it Blue #56?).
For no reason whatsoever, Tommy's father in Rugrats has purple hair. In the All Grown Up spin-off, Tommy inherits his father's unnatural hair color, suggesting that it's actually genetic.
Most of the human characters in Phineas And Ferb have plausible hair colors, except for Ferb, who has green hair.
- Also, most animals are colored somewhat like they are in real life, except platypi, which are all colored bluish-green.
While not an anime, Jem fits into this trope. While one could argue that most of the characters are just dyeing their hair, since they're all rockstars, but a flashback to the main characters childhoods reveals that no, with the obvious exception of Jem (being a hologram and all), all the kids had blue, purple, and pastel red hair even when they were kids. The heck?
Aelita from Code Lyoko has natural pink hair both in her Lyoko avatar and in the real world. She inherited it from her mother, who is shown in flashbacks to sport the same hair color. It stands out as the rest of the cast has a normal range of hair colors for French kids (assuming Odd's purple spot is permanently dyed).
- Well, most of the rest of the cast. William's mother has green hair, as well as a DJ girl prospect in the episode "Crash Course". And Chris Moralès is a White Haired Pretty Boy.
- Odd's mother has mauve hair.
Many characters on Invader Zim have oddly-colored hair.
- Interestingly, every significant female character seems to have either blue or purple hair — Gaz, Tak in her human disguise, even Zita and Gretchen. The only exceptions are hairless aliens and characters too small to really care about.
Nobody ever explains why Elisa Masa of Gargoyles has blue hair.
Most fairies on The Fairly Oddparents have weird hair colors: Wanda has pink, Cosmo green, Poof purple, and Mama Cosma blue.
Danny Phantom from Danny Phantom has this going on. In human form, his hair is black, but when he "goes ghost" it turns white—and glows, apparently. And some of the ghosts have strange hair colors—Ember's hair is blue (and on fire), Kitty's is green, and Technus's is also white. Otherwise, it's a normal range. (The series does suffer from Technicolor Eyes, though. There are no characters with brown eyes. Even the African-Americans are green-eyed...which really doesn't make sense, but hey.)
Frida of El TIgre has bright blue hair. So does her father and her unseen grandmother, implying that it is genetic. That, or certain members of the Suarez family must dye their hair blue.
Chris from Monster Buster Club has blue hair.
In Trollz, most of the characters have oddly-colored hair. Amethyst has pink, Sapphire has blue, Onyx has purple, Coal has green...Oddly enough, Ruby's hair, fire-engine red, is stated once to be dyed. Her natural color is brown.
In Ka Blam!, Henry has green hair, June has sky blue, and Loopy has robin's egg blue.

Keeping to its policy of uber-realism, all the characters in Welcome to the NHK have black hair.
Most characters in Neon Genesis Evangelion have black hair, except Asuka, the But Not Too Foreign redhead, and Rei and Kaworu, who we'll excuse due to the weirdness surrounding their nature. Ritsuko is a natural brunette with a blonde dye job (she missed her eyebrows). Also, we're going to say Misato has stylized black hair, not purple. Change this if Word Of God says her hair is purple.
- Basically, this means that Eva is an impossible hair show with justification.
- Misato's hair is properly black in Rebuild of Evangelion.
  - In the manga, it looks much more like stylised black. A number of other subtle-but-unlikely colours are also changed, including Shinji reverting to brown eyes instead of blue.
- The Rebuild art for the new character Mari Makinami started out realistically with dark hair, then brown in most official pics, then... purple in the merchandise like the keychains and the plugsuit art. Figures.
The protagonists of Fullmetal Alchemist have blond or light brown hair, but given that the show takes place in a thinly-veiled inter-war Germany, it's plausible.
- But then there's Rose, who has pink hair...
  - She is probably dyeing her bangs, as the rest of her hair is dark brown.
  - In the second anime, Rose is shown to have bangs that are brown, just slightly tinted redder than the rest of her hair.
- Also note that in the manga, having blond hair and golden eyes like Ed, Hohenheim, and manga Al is shown to be a characteristic of ethnically Xerxian people. Also, while in the anime, Ishballans had dark hair and Scar's was implied to have turned white as a side effect of either trauma or his brother's sacrifice, in the manga, all Ishballans have white hair.
  - In the new anime, they appear to be a race of DarkSkinnedBlondes with red eyes.
Almost everyone (minus the half-foreign girl) in Sayonara Zetsubou Sensei has black hair, which is odd considering how strange the show is about everything else.
Most of the characters in Irresponsible Captain Tylor have either brown or black hair. The only exceptions are either characters of non-Japanese descent (such as Harold or Jason), greying (Mifune and Hanner), or aliens (Azalyn, Dom, and Shia Has). Much like Zetsubou Sensei, this is surprising considering the nature of the show.
Any non-black-haired Inu Yasha character is a demon or part-demon, and even many of them have black hair. When depowered, Inu-Yasha's hair becomes black.
Cardcaptor Sakura. Even the mages have brown or black hair. Fall outside this and you're a being created completely by magic.
- Except for Kaho Mizuki, the red-haired Japanese woman...
- In the manga cover artwork, Sakura has been shown in varying degrees of blonde, from yellow blonde to strawberry blonde. Tomoyo's hair has been shown to be purple rather than stylized black, and Sakura's mother, Nadeshiko, has greenish brown hair in the anime and purple hair in the manga like her first cousin once removed, Tomoyo.
The .hack// franchise, but you'd never know by looking at it. The technicolour cast you see on screen is represented by their online avatars, and all their real life selves have brown or black hair. Hotaru doesn't count.
Black Lagoon, all Asian characters have dark hair, some western characters have blond or red hair.
Almost all characters in Mermaid Saga have black or brown hair, with the exception of one woman whose hair turned white due to severe trauma.
Mushishi plays this one straight by having everyone have black or dark brown hair, unless they've been Touched By Vorlons or have something else supernatural about them.
Genshiken is high on the realism, as befits its slice-of-life nature. Almost everyone has black or dark brown hair, and the rest use artificial colouring.
Everyone from Earth in Magical Girl Lyrical Nanoha has brown hair except for Alisa (who's American) and Suzuka's household (which still fits if taken as a Mythology Gag, as they're adapted from a family in Triangle Heart 3 Sweet Songs Forever composed of Japanese Vampires and Robot Girls). Blonde Fate passes as a "foreign exchange student" in the second season because of this. People from magical worlds have all kinds of hair colours.
- It should be mentioned that the Triangle Heart 3 Sweet Songs Forever OVA contains a veritable rainbow of hair colors. But then again the game itself is a Fantasy Kitchen Sink, so...
A few people's hair edges towards slightly too light in Serial Experiments Lain, but otherwise, everyone has black or deep brown hair.
Everyone in Paranoia Agent has naturalistic brown, black or grey hair. The art is also notable for being detailed and realistic enough that you can actually tell characters apart by their facial features.
Suprisingly for a shonen series, the hair colours in Soul Eater are largely made of light and dark brunettes with a smattering of blondes and redheads. Which considering the series is set in the global headquarters of an organisation in America is perfectly acceptable. The only exception is Black Star's changing colours(greens, bright reds, blues, whites), and Death the Kid's streaks, the latter of which is remarked upon and lamented by the character(and justified in that he's not human) and the former is the kind of person who would die their hair outlandish colours to stand out. The remaining outlandish colours belong to monsters and witches, who don't really have to follow the rules. Soul Eater, however, has pale gray, almost white hair.
- In Kid's case, his striped hair is actually a plot point, the white 'Sanzu Lines' being a trait of shinigami that change according to age.
Chrono of Chrono Crusade has purple hair, and Aion has white hair, but considering that they're both demons this could just be pointing out their odd nature. Azmaria has white hair, but also has red eyes and pale skin, so she could be an albino. The rest of the human cast range from blonds to redheads to black hair, but since the anime is set in America it's not that odd to have the heroine be blond and blue-eyed.
Seras from Hellsing is a light blonde (or redhead, depending on the production), and Sir Integra is a platinum blonde; justified, because both are British.
Angel Densetsu is grounded in reality, so people with unusual hair colors stand out, and it's almost always dye-jobs. Ogisu for example has bright red dyed hair that he uses to intimidate people and look unique. It doesn't work on the protagonist, who thinks he's suffered a head injury and accidentally knocks him out in a fervent attempt to get him to the nurse's office.
- Deconstructed with Yuji, he has natural light brown hair, and people bothered him for the "dye job". So he bleached them blonde to be even more of a yankee. (usually asians get reddish-orange hair with a bleach, you get blonde only if you start out brown)
Ghost In The Shell has characters with hair colours like purple and aqua, but since people have access to fully-cybernetic bodies, it's justified. It's also quite rare, the vast majority of characters still have brown or black hair.
In Planetes, everyone has realistic hair colours, and the shades are always appropriate to the country of origin (even if having a reddish-brown Japanese woman is pushing it a bit).
- In the manga, at least, Tanabe is adopted, so that's okay. Clare's weird green hair thing, however...
All the characters of Youre Under Arrest have realistic hair colors.
Justified in Yokohama Kaidashi Kikou in that the robots have unusual hair colors (green for Alpha, pink for Kokone), but all the humans have realistic hair.
The characters of Patlabor feature realistic hair colors. Noa's red hair is a bit unusual for a Japanese person, but not impossible.
The characters in Legend of Galactic Heroes have realistic hair colors, for their races at least. The redheads and blondes are usually Caucasian, and the Asians are limited to brown and black.
- Except for main character Yang Wen-Li who is usually shown with... dark blue hair.
  - What, no-one mentions Dusty Attenborough? His hair is "green" for heaven's sake! And it's not like the Alliance Military allows dye-jobs... or "does" it?
All of the characters in Samurai Champloo have black, brown, or grey hair, save for foreigners and couple of very obvious bottle blonds. The pink-haired old man from episode 21 appears to be an exception to the otherwise realistic hair colors, but, pink hair dye is probably available in the show's version of Edo Japan.
The characters in Axis Powers Hetalia are all drawn with realistic hair colors, though there is a large number of blond countries.
Every character in Kimagure Orange Road have hair colors from tan-brown to brown to black. Except Jingoro, but he is a calico cat.
Kaleido Star: The show takes place in the United States, and the central character is Sora, a Japanese girl who has moved there. Everyone in the cast has normal hair colors, ranging from blonde to strawberry blonde to black, except for Sora, who has purple hair. (Even the other native Japanese who visit her have realistic hair colors.)
- Objection! Anna Heart, an American, also has purple hair.
Kazuma of Nora has normal, if a bit spiky, black hair, save for two blond chunks in his bangs (it could be dyed, but... isn't he supposed to be Student Council President?).
Digimon tends to have mostly natural-for-humans hair colors (the odd purple head does show up) but it's got a lot of brown, blond, and red hair for an all-Japanese cast.
In Martian Successor Nadesico, Ryoko has green hair. However, in a flashback to her childhood, she has brown hair. In other words, she's clearly dyeing it. (Now what to make of Yurika's violet hair...)
Rosario + Vampire features some funky hair colours in Mocha and Kurumu, being bright pink and light blue. Averted elsewhere.
Android Announcer Maico 2010 has normal black or brown hair for the human (Japanese) characters, and pink hair for Maico - but then, Maico is an android.
The very large cast in Detective Conan has hair colours expected for the Japanese population, with the exception of Ai, Hakuba and American females.
The majority of classic manga author Go Nagai's works avert this trope, going for the all-black route. The main major exception to this is Cutey Honey, but otherwise he seems to avoid unnatural hair colours even in his less serious manga such as Mazinger Z.
- Honey's (usually) blonde hair is justified, as even without her Master Of Disguise powers, she's still a bio-android of some sort.
- His protégé Ken Ishikawa is much the same. The only character in Getter Robo he designed with an implausible hair colour is redhead Shou, though it's not unheard of in Japan.

Silent Dragon, which is set in Japan and heavily inspired by anime, has the redheaded Renjiro and the blonde Suki. However, Renjiro is an android (he has black hair in his human body), and Suki is an obvious dye job.
You might think Noriko (Surge) from X-Men isn't like this, as she's a Japanese girl with blue hair. However her hair is Black in her first appearance as a homeless girl in New Mutants and in one panel of New X-Men: Academy X she stated "It said electric blue on it and I couldn't resist." She keeps her hair blue for the rest of the series.

Coraline in The Film of the Book has blue hair. Though at one point there is a picture of a brunette Coraline with her parents. We're dealing with an eleven-year-old rebel here.
- Which is also a nice subtle hint that her parents aren't quite as uncool as she's making them out to be.
- It can also be interpreted as her way of getting her parents' attention (it didn't work). Seeing as most examples on this page are from Manga and Anime, it also displays a subtle pattern of nerdiness that not everyone picked up.

In Keys to the Kingdom by Garth Nix, Superior Saturday has electric blue hair.
In the sixth Hitchhiker's Guide to the Galaxy book, Ford Prefect acquires blue hair by way of a dark matter-powered ship that can basically do whatever you want to your body.
Tonks in Harry Potter has pink hair most of the time. She is a Metamorphmagus (able to change her appearance as she likes) and has appeared with violet, blonde, red, grey and mouse-coloured (the natural colour) hair in the books.

The protagonist of the Wing Commander series, called "Bluehair" by his creators (and later named Blair as a reference to his blue-haired days, when he's played by Mark Hammill). This was a result of the limited color palette available to VGA displays of the time.
A major rule in Lufia is that if you see a girl with blue hair, you're looking at this game's incarnation of Erim, Sinistral of Death. The one exception, Iris from the second game, has green hair that turns blue once The Reveal hits.
In the Soul Calibur Ivy and Cervantas have ghostly white hair (Ivy apparently even had it as a child) both are the results of Soul Edge. Tira in the 3rd game has blue/green hair, but she is covered in bodypaint and her hair is black is the 4th game.
- For Create-A-Soul (and by extension, Chronicles of the Sword, where a few preexisting examples exist) however, this is in full force, most likely for use with every other example here.
Carmelita Fox in the Sly Cooper games is a blue-haired vixen. In game 2, she gains a partner, Neyla, who seems to be a pink- or purple-furred tiger (her head's always covered so one can't see hair there). The only other named female, Penelope, is a blonde mouse.
Cham Cham from the Samurai Shodown series is either a green- (player 1 colours) or blue- (player 2 colours) haired Cat Girl. Everyone else seems to have realistic hair colours (or, in many cases, nonexistent hair).
NPCs in Pokémon games often have unusual hair colors, but player characters are generally immune to this. Kris in Crystal is an exception to this immunity, as she has bluish-green hair, while Lucas and Dawn in Diamond, Pearl, and Platinum appear to have blue hair in their in-game sprites, though it sometimes looks black elsewhere (such as in the strategy guide for Platinum). Brendan in Ruby, Sapphire, and Emerald is a strange case, since most art and sprites of him seem to show black sideburns visible beneath his "hat"/headband/whatever-it-is, but the only piece of official art that shows the back of his head shows the white part◊ extending beneath it. The actual colour has never been confirmed.
- The hair of Gen IV villainous teams tend to be the most outrageous. In the original games, most Team Rocket members had red, brown, or black hair. In Heart Gold and Soul Silver, all grunts now have pink hair. Even the males. Their classic black and red uniforms haven't been altered, so the pink hair just seems odd. Meanwhile, Team Galactic seems to have raided a hair salon, as every single grunt has bright blue hair. The commanders have dark blue, crimson, pink, and light purple hair respectively. Compared to all of that, Cyrus's bluish gray hair seems almost normal.
The Star Ocean series does this all the time, and blue is particularly common.
- Justified in that the only humans with abnormal hair have genetic modifications which, according to the page intro, make their blue hair plausible. Everyone else with odd hair color is an alien.
  - There is one earthling with blue hair that wasn't genetically modified. The mother of the third game's main character has hair the exact same color as her son.
Every normal human being in Okami has black hair if it hasn't gone grey from old age, due to the game being set entirely in ancient Japan. The inhabitants of Wep'keer get a pass for their odd hair colors due to apparently being a race of magical dog-people, while blond hair denotes being a member of the otherworldly Tribe of the Moon.
A few of the dancer characters in Dance Dance Revolution have unusual hair colors. I can name Rena and Emi, mascots of Hottest Party and the other DD Rs respectively. There's also U1, who can come with blue or purple hair. jun who comes with pink hair. There's also Root, with brighter-than-normal orange hair. and even U.G. with that epic rainbow afro of his! Ohh, and there's also Alice who has blue hair.
Pick a Ryu in Breath Of Fire I-IV. Any Ryu. Pretty much the walking example of the Plausible variant of this trope.
- Justified here in that all Ryus (save in Dragon Quarter) canonically are dragons of some sort, and furthermore live on planets full of Petting Zoo People. Dragon Quarter shows examples of the other variety of this trope with its own Ryu.
Gaia Online's human NP Cs are ironically immune to funny hair colors, though of course anything goes with the users. The few blue-haired NP Cs who show up (Jinx, Sam, and Timmy) all have really dark blue hair, possibly meant to be blue-black. Rina's brick-pink hair darkened to brown when she grew up. Natasha is canonly mentioned as bleaching hers white. The Overseer is excused by virtue of being a former demigod.
- MTV sponsor character Julie manages to invert the trope completely by being the only Gaia NPC with dirty-blonde hair, as opposed to the cartoonishly-bright hair colors of the other characters.
Played with in BlazBlue. The human characters all have normal hair colors. Ragna's prematurely-white hair is the result of childhood trauma. Nu's white hair comes either from being an Artificial Human or prolonged exposure to The Boundary. Hakumen's white "hair" is actually part of his armor. Kokonoe's pink hair marks her as half-beastman (as if the ears and tails weren't a giveaway.) And Hazama's green hair indicates that there's something not quite right about him.

PeeJee in Something Positive has an range of odd hair colours, usually purple. It's dyed.
Pretty much everyone in Megatokyo has completely possible hair colors: Piro is an American blond, Largo is an American redhead, Kimiko and Erika are Japanese brunettes, and Yuki and Dom have black hair. The only exceptions are Miho, who dyes her hair purple, and Ping the Robot Girl, who shifts through several animesque colour schemes.
In Misfile, most characters have believable shades of red, brown, or blonde hair. However, Vashiel and Rumisiel have different shades of grey, dispite only being teenagers, and Emily's hair is blue (although only apparent in the few color pictures). Vash and Rumi are angels, so they have an excuse, but Emily is a normal human. Some fans believe that Emily has black hair and is only colored blue for shading, but Word Of God hasn't confirmed either as of yet.
Aggie of Penny And Aggie has blue hair, and her friend Lisa's, at least as depicted on the cast page, is various shades of unnatural red. Since both are considered members of their high school's "alternative" culture and the strip in general is realistic, it's safe to assume the colours are bottled.
- Katy-Ann also has pink hair, which she explicitly said was dyed in a recent strip.
  - Aggie had brown hair before her teens.
  - According to Word Of God, Lisa's natural hair colour is also brown.
- Xena has silver hair, as seen here.
Molten Blade features mostly normal hair colours, although a few characters have more vibrant shades than would be expected in reality, eg. Fred's yellow hair and a minor character with dark blue hair
In Get Medieval, a panel awarding grants for scientific research is a bit unsure about an applicant who has dyed her hair pink. Another member of the board points out that actually she is from a planet with a rather broad idea of acceptable genetic modifications.
In Namir Deiter, siblings Roxanne, Blue, and Issac all have blue hair (inherited from their mother). Joy also sported pink fur, but that turned to be a (since discarded) dye job.
- Joy's regular fur is pink. Her undercoat is white, which is revealed every winter when she sheds her pink fur. She did, however, go through a phase where she intentionally bleached her fur white, but this caused problems and required a doctor visit (who prescribed Hare Tonic...yup).
Tom from Khaos Komix has orange hair, and Charlie has green, both dye-jobs. Charlie's case is probably partially Anime-inspired.
Sinfest's Monique has purple hair.
The genetically-engineered furries in Jack have a wide variety of odd fur colours. Jack himself is a green rabbit, Drip is a blue rat, and Vinci is a purple raccoon.

In the Whateley Universe, Tennyo has Ryoko's light teal hair color and hairstyle because of the way her mutant powers manifested in her first story. She's stuck like that.

Pepper Ann's Milo Kamilani has extremely dark black hair, which "projects an iridescent blue sheen".
Avatar: The Last Airbender is one of the few fantasy worlds to have significantly fewer hair colors than in real life: Suki has auburn hair. Yue has white hair (which was an effect of being healed by the moon spirit). Everyone else's hair is brown, black, or white/gray from old age. This is probably because the series is set in an obviously Asian-influenced world. Asians in Real Life typically have dark hair.
One of the Kanker Sisters on Ed Edd N Eddy sports blue hair, and it's never made clear whether it was just a creative coloring choice or just another sign of the sisters' lawlessness and lack of supervision.
Titan AE's sole Japanese character, Akima, has (partially) purple hair. This might not have been intentional, but it's still rather uproarious when thought about.
Although the second Teenage Mutant Ninja Turtles usually portrayed people with realistic hair colors (unless it was obviously dyed), two exceptions stand out: mutated human Sydney, whose hair is shown to be blue when she reverts back to human, and Mr. Mortu, whose human disguise sports hair colored a light shade of purple, despite the fact that his cover is that of an executive at a company.
Then you have Transformers Animated and Sari, whose hair is magenta.
The Judge from Science Court has aqua hair.
Leela from Futurama has purple hair.
Just try to name a character in ReBoot that doesn't have a weird hair colour. We have Andraia who has turquoise hair, Dot, Enzo and Matrix who have really dark green hair, Bob who has silvery gray hair, and Mouse who has red/orange hair that looks like radio static. Justified though, seeing as they're in a different dimension.
