Anime & Manga
- Half the hair on Jio's head from 666 Satan is white, to go along with his heterochromia. Being possessed by Satan does wonders for his personal appearance. After the Timeskip, the wonders aren't just for his hair, but his hair still is one hella uncommon for the place where he lives.
- In Black Jack, half of Dr. Black Jack's hair became white after a land mine blasted his head apart when he was a child.
- In New Mazinger -a Mazinger Z spin-off- Major Kabuto is black-haired, but his hair's central part is red.
- Yugi Mutou has purple, black, and blond hair, and it is implied that his grandfather looked like this when he was younger.
- The Pharaoh was shown with these hair colors when he was born, but his dad has black hair, like a normal Egyptian. Some suspect that he got his hair from his unseen mother; on the other hand, anime hair doesn't exactly have to follow logic and science.
- Almost everyone from Yu-Gi-Oh! ZEXAL has this to various extents. For example, Yuma's is pink and purple.
- Hikaru from Hikaru no Go has mostly black hair; his bangs are blonde.
- Rosé Thomas from Fullmetal Alchemist has dark brown hair with pinkish brown bangs.
- Nia from Tengen Toppa Gurren Lagann has pastel blue and yellow hair, layered in such a way that one might think the blue parts were the shadows at first. Slightly less noticably, Kittan's is blond on top, but the sides, back, and eyebrows are either brown or black.
- Guts of Berserk gets a white streak in his hair after using the cursed Berserker Armor for the first time.
- Fruits Basket: Hatsuharu has black and white hair because his animal is the cow. He's the only one accused of dying his hair an "unnatural color", despite the rainbow varieties among the cast not likely to be found in Japan, because it looks like his roots reveal the natural color. At least for the others, it's one color per person. (He promptly demonstrates his innocence, with the expected results.)
- Birdy from Birdy the Mighty has strange red and white hair; its exact appearance varies depending on the adaptation.
- Hinoki Sai from Betterman. She has brown hair with the exception of her bangs which are red and green. Although the majority of her flashbacks suggest that the rest of her family have the same unusual quality.
- Seikichi from Oh Edo Rocket has a spiky orange fringe in the front and a fairly normal brown ponytail in the back. Interestingly, it's similar to Negi below, and Sora comments on this in a dub Actor Allusion.
- Yoshikage Kira from JoJo's Bizarre Adventure part 4 gets Norman Osbourne green-and-black stripes at one point.
- Death the Kid from Soul Eater has black hair with three white stipes that only cover half of his head, a fact that greatly annoys him because he has OCD and is extremely obsessed with symmetry. This is in a series where many characters have close-to if not exactly realistic hair colours. Kid's case is unusual and down to genetics (for want of a better word).
- Death is a Shiningami and those lines are the Sanzu Lines. When they connect, he will become a full Shiningami and succed his father. Near the end, he connects all of them, Lord Death fades into dust, proud of his son growing up.
- In the world of Strike Witches, where Magical Girls grow animal ears and tails when using their magic, Erica Hartmann just gains black highlights at the ends of her bangs.
- Macross Frontier. Sheryl Nome has pink hair with blonde highlights, or vice versa.
- Olivie from Angelique (blonde/golden and dark pink/red). Some character designs also threw green into the mix.
- Anzu from Hanamaru Kindergarten has her mother's blonde hair in the front and her father's brown hair in the back. This is completely natural.
- Gotenks from Dragon Ball Z, being the result of a Fusion Dance, has purple and black hair.
- Negi and his father, Nagi, from Mahou Sensei Negima! have auburn hair on the top and black hair in the back.
- In Kämpfer, when Shizuku activates her Kampfer power, her hair turns white on the inside, sometimes rainbow.
- Nurarihyon No Mago:
- Rikuo's normal hair is brown on top and black in the back and when, turned into a demon, his brown hair turns white.
- Yuki-Onna/Tsurara has a hair color similar to Rikuo's demon form as well, only bluer.
- Gyuuki's hair is green and black in the same pattern as Tsurara's.
- Sena of Eyeshield 21 has brown bangs, while the rest of his hair is black. This is probably a case of Author Appeal, since the main character of the artist's other manga, Blust, has black bangs with brown hair.
- Stocking from Panty & Stocking with Garterbelt has dark blue hair with pink highlights. Furthermore, her hair seems to be blue on the outside and pink toward her scalp.
- Urusei Yatsura: Lum in the manga had full-blown rainbow-colored hair that seemed to shift colors, yet this is hard to tell because colored images of it were often inked over a majority of it. As the manga progressed, Rumiko Takahashi changed Lum's hair color to green to match the anime, as it was changed there.
- For most of the series, Bleed Kaga from Future GPX Cyber Formula has green hair with orange triangles on each side of his hair and a black tail.
- Star Driver's Takuto has deep red hair normally, but gains a brighter red color and yellow bangs when he Apprivoises.
- In Ranma ˝:
- In the manga, the rare color renderings of Akari Unryű give her greenish hair with two pink stripes.
- Prince Herb of the Musk Dynasty (pronounced like the plant, not "Herbert") has long white hair that goes pink at the ends, except for his front bangs, which are navy blue.
- Kaite Madigan from Gundam SEED Astray has black and blond hair as a result of his genetic enhancements not coming out quite right. His parents gave him up for adoption because of this.
- Rebecca Miyamoto from Pani Poni Dash! has hair that is part blonde, part pink. Presumably, it's because she's half-American and half-Japanese.
- Ground Control to Psychoelectric Girl's Erio has very light blue hair but at times gains crystal-like glitter (that can flow off her without ending). Other characters notice this, mainly Makoto, but never mention it out loud.
- Potemayo is full of gradient-haired characters, and some of them are two-colored, such as pink/blonde on the titular moeblob, purple/magenta on Guchuko, and blue/green on Nene.
- Itsuka Tenma no Kuro Usagi has several examples of gradient hair. Himea has pink to blue hair with sparkles, Haruka has brown hair with purple ends, Aomi has a similar style with yellow hair, and Mirai occasionally has yellow to purple and light blue hair.
- Gai from Saint Beast has blond hair with brown tips.
- A short-lived Bleach villainess, Berenice Gabrielli, had white and black hair.

- When the magical girls of Il Sole penetra le Illusioni transform, their hair gets rather longer and gets a gradient effect. Fairly subtle for most characters, but Priscilla's starts brown, turns red, then ends up white.
- Kill la Kill
- Heronie Ryuko Matoi has black and red hair.

- In the epilogue of Rosario + Vampire, Moka's hair turns white and pink, since her two personalities have become one.
- The Sandman:
- Delirium has blondish-reddish-purplish-whatever-she-feels-like hair. It both changes color on a regular basis and is generally multicolored at any given time.
- Rose Walker also has multicolored hair. It's blonde, red, and blue in The Doll's House, and then red with a blonde streak when she resurfaces in The Kindly Ones. Toward the end of the series, possibly as a symbol of finally coming to accept herself, she goes back to her natural color . . . which is puce. (Her grandmother and mother are also shown to have this hair color, meaning that yep! it's real.)
- Melaka Fray from the comic books Fray and Buffy the Vampire Slayer has blue and purple two-toned hair.
- Rogue of X-Men has a white streak in her brown hair. Jury's out as to just how she got it.
- The Movie: Locked into Strangeness;
- The Comic: Flip Flop of God. Initially, she was drawn to be a woman in her sixties—the white streak was graying hair. When her age was settled down at being seventeen, the white streak was referenced as being dyed. When her backstory was established, she had the white streak even as a thirteen-year-old. While it's possible it was dyed, fans were unsure, since the placement of the white streak varied quite strongly whenever her look was changed. Finally, in her solo series, her hair is shown with a white streak from when she was a toddler, making it a physical mutation.
- Norman Osborn from Spider-Man is drawn with red hair with black stripes, though it's possible that his hair is just in waves and that the red is to show the raised areas.
- Batman's Two-Face has black hair on his normal side of his face and white hair on his scarred side (when artists don't just make his left side bald).

- Melissa Gold, a.k.a. Songbird of the Thunderbolts has white hair with pink streaks. It's apparently natural.
- War of Kings, trying to make the Inhumans look more, well, inhuman, drew the dark stripe and circle in Crystal's otherwise reddish-blonde hair, which in earlier stories seemed to be a weird hairband, as her actual hair colour.
- Abby in Swamp Thing has white hair with a black streak on each side - sort of reverse Skunk Stripes.
- Nestis Towadi from DJINN Way To Home has platinum blonde hair with brown streaks, the result of the Mixed Ancestry from her Native American father and blonde mother. Nestis is sensitive about her unusual coloration, but the only person who criticizes her hair is the local Alpha Bitch. Everyone else loves her look, especially Ingrid Hale who is borderline obsessed with Nestis' hair.
- From Kill la Kill AU, Ragyou also has this true to canon, usually. It also serves as Kaleidoscope Hair, apparently, as it reacts to her mood, as was shown in a few comics.
- Light and Dark The Adventures of Dark Yagami takes this Up to Eleven, when Dark transforms into Du'arq, his Shinigami form, his hair is said to change to "every color of the rainbow but only in dark black like oil or something."
- Detsniy Off Skiword has used this at least twice. In his Kid Icarus fanfic, Pit2 gains "Dark Black Rainbow Hair" in his Super Mode. In his Nintendo Wars fanfic, his new CO, Dusk, is said to have hair that is black and blue.

- In Poltergeist, Diane Freeling's trip through the afterlife to rescue her daughter leaves her with a streak of white at each temple. She is reluctant to dye them back, thinking they look "punk" (and possibly seeing them as a badge of pride).

This hair was settled strikingly into three coils on the cleft at the back of his head. Each long loose-flowing strand hung down in shining splendour over his shoulders, deep-gold and beautiful and fine as a thread of gold. A hundred neat red-gold curls shone darkly on his neck, and his head was covered with a hundred crimson threads matted with gems.
- As noted above, Cruella de Vil of The Hundred and One Dalmatians had hair that's half-black, half-white. After she goes through a short but thorough Humiliation Conga that was sadly left out of the Disney version, the black half goes white and the white half goes green, apparently from stress.
- Louis Veyrenc de Bilhc, from Fred Vargas' novels (introduced in This Night's Foul Work), has brown hair with red stripes. This is because when he was a child, he had been attacked by kids from the neighboring village ; they had slashed his scalp with glass shards, and where he had been cut, his hair grew back red.
- Artemis Fowl: The Lost Colony has Billy Kong, a mercenary with a criminal record in Taiwan, who nevertheless has several (unspecified) colors in his "manga hair." Fridge Brilliance may be involved here: it's implied that this, plus his slight build, leads people to underestimate him and not suspect that he's a professional assassin.
- One of Harry Dresden's best friends throughout the series is Michael Carpenter, the devout, comically-serious Fist of God. Capital-G God. His wife, Charity Carpenter, is the severe mother of a veritable litter of kids. The descriptions of their eldest daughter, Molly, always start with what color(s) her hair is that week.
- The Alethi in The Stormlight Archive have black hair, but if you are not pure-blooded Alethi your hair will naturally be a mix of black and something else, such as blond or auburn.
