A list of Western animated shows in which characters have unusual hair colors.

----
* Taken to an extreme with ''{{Doug}}'', which not only has a rainbow of hair colors, but [[AmazingTechnicolorPopulation skin colors]] as well. Doug's best friend Patty is a DarkSkinnedBlond, and his other best friend Skeeter has blue skin.
* Ignoring the yellow skin, the characters of ''WesternAnimation/TheSimpsons'' 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 are 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?). Also subverted with Patti and Selma. [[spoiler:Their true hair colors were hidden under smoke and ash.]]
** Chief Wiggum also has blue hair, but it was black in early episodes.
*** Millhouse too
**** and the "Blue-haired Lawyer"
***** When Waylon Smithers was an African-American in the episode "Homer's Odyssey," he also had blue hair.
* Turanga Leela from ''WesternAnimation/{{Futurama}}'' has purple hair, though it might be justified. She is a [[spoiler: mutant]].
** Leela's mother has purple hair and her father has blue/gray hair.
*** Igner also has pink hair.
* Mayor [=McDaniels=] from WesternAnimation/SouthPark has turquoise hair, while Nurse Gollum had pink hair. While most characters' hair is colored within the plausible range, there were occasions where background characters would sometimes be given bright blue or purple hair.
* In ''WesternAnimation/{{Gargoyles}}'', [[ActionGirl Elisa Maza]] has a defined shade of dark blue hair, despite most other characters having more realistic tones of hair color.
** Technically, it's blue-black.
* For no reason whatsoever, Tommy's father in ''{{Rugrats}}'' has purple hair. In the ''AllGrownUp'' spin-off, Tommy inherits his father's unnatural hair color, suggesting that it's actually genetic.
** The same can be said with Didi's pink hair that Dil inherits.
* Most of the human characters in ''WesternAnimation/PhineasAndFerb'' 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.
*** Except the stuffed one in the museum at the end of the chariot race, which is '''[[RealIsBrown brown]]'''
* ''{{Jem}}'': one could argue most of the characters dye their hair, since they're all rockstars, but a flashback to the main characters' childhoods reveals that, 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.
* Aelita from ''CodeLyoko'' 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 has white hair.
** Odd's mother has mauve hair.
* Many characters on ''InvaderZim'' 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.
* Most fairies on ''{{The Fairly OddParents}}'' have weird hair colors: Wanda has pink, Cosmo green, Poof purple, and Mama Cosma blue.
* Danny Phantom from ''DannyPhantom'' 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 [[TechnicolorEyes 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.)
** Ever heard of Cape Verde?
* Frida of ''ElTigre'' 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 ''WesternAnimation/MonsterBusterClub'' has blue hair; [[{{Irony}} Ironically he's not the team alien]].
* In ''WesternAnimation/{{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 ''TotalDramaWorldTour'', Sierra has completely violet hair, it's unknown whether it's "real" or dyed. Gwen and Duncan also have teal and green respectively, but it's dyed.
* In ''WesternAnimation/KaBlam'', Henry has green hair, June has sky blue, and Loopy has robin's egg blue.
* Rejected {{Nickelodeon}} pilot ''The Modifyers'' has Agent Xero with pink hair as her normal look and blue hair for her PerkyGoth alternate identity Lacey Shadows
* Speaking of Nickelodeon, ''MyLifeAsATeenageRobot'' gives us [[{{Robot Girl}} Jenny]].
* Tasumi from ''WesternAnimation/TheReplacements'' appears to have blue hair...but only when she's wearing her armor costume. When she removes it later in the series, it's revealed she's actually [[spoiler:a brunette.]]
* On ''PinkyDinkyDoo'', Pinky's hair is pink and her brother Tyler's is blue. In the original books, Pinky's hair was yellow and Tyler's was pink, until the book ''Think Pink''.
* On ''LadyLovelyLocks'', the eponymous character's eponymous locks are blonde with purple and pink highlights.
* Gumball and his mom, Nicole, from ''WesternAnimation/TheAmazingWorldOfGumball'' have blue ''fur''. His sister, Anais, and father Richard are pink rabbits.
* As do the titular characters of ''TheBrothersFlub''.
* Many of the bird characters on ''WesternAnimation/{{Birdz}}'' have blue feathers, including the Storkowitz family and Miss Finch. Sleepy Bat, the only non-bird in the series, also has blue fur.
* All the ponies from ''MyLittlePony'' (including ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic Friendship is Magic]]'') have wildly varying colors of coats and manes, almost none of which are possible in real life. This includes Rainbow Dash, [[MeaningfulName whose mane spans almost every color in the rainbow]], and Twilight Sparkle's big brother Shining Armor, whose mane is striped in three shades of blue.
** In the movie spinoff, ''WesternAnimation/MyLittlePonyEquestriaGirls'', while [[spoiler:the ponies are human, they keep slightly faded versions of their candy-colored skin and hair.]]
** This was enforced, as the animators [[FlameBait didn't want to give the ponies a canonized ethnicity]].
* Gil on ''WesternAnimation/BubbleGuppies''. His CurtainsMatchTheWindow. Goby also has dark indigo hair and Oona has purple hair.
* In ''HiHiPuffyAmiyumi'', a particularly bizarre case, wherein one character has razor-cut blue hair and the other cottony pink hair (the latter also has anti-gravity pigtail-like spheres of hair above her head). The bizarre part is that the characters are supposed to represent [[http://www.puffyamiyumi.com/ two actual people]], both of whom[[note]]typically[[/note]] sport long, wavy black/brown hair.
* In ''TeamUmizoomi'', We have Geo and the Blue Mermaid, who both have blue hair.
* As Soar Loser in ''WesternAnimation/SkysurferStrikeForce'', Brad Wright dawns a lime green wig. Bioborg, Dr. Five Eyes also has lime green hair.
* Mara in ''TronUprising'' has light blue hair; this is notable because almost every other program in the Grid has black, dark brown, or grey hair.
* Tommy Anybody from ''WesternAnimation/{{Mr Bogus}}'' has orange hair.
* In ''WesternAnimation/TheMrMenShow'', Miss Naughty has pink hair and Mr. Persnickety (AKA Mr. Fussy) has green hair.
* ''SeaPrincesses''
* In ''TheSecretSaturdays'', Epsilon's son Francis has green hair.
* Florence Papermouth in ''MoralOrel'', one of the only characters from this show to fall under this trope.
* Kaia in ''{{WesternAnimation/Motorcity}}'' has green hair.
* In ''TheSecretShow'', Professor Professor has green hair, Special Agent Ray has blue hair, and Doctor Doctor has blue hair and blue skin.
* On ''[[WesternAnimation/StrawberryShortcake Strawberry Shortcake's Berry Bitty Adventures]]'', only Orange Blossom and Huckleberry Pie have realistic hair colors (dark brown and medium brown respectively). Strawberry gives "redhead" a whole new meaning, and despite Lemon's blonde moments, her hair is definitively yellow. Cherry's hair is a deep purple and occasionally sparkles. Blueberry, Plum, and Raspberry's hair colors can't be found anywhere outside a bottle in the real world.
* Courage from ''WesternAnimation/CourageTheCowardlyDog'' is a dog of an unspecified species with pink fur.
* ''WesternAnimation/RatedAForAwesome'': Les. Also, Thera has purple hair, and Noam has green.
* Many of the ''[[Disney/WreckItRalph Sugar Rush]]'' racers have odd hair colours, as befits their confectionery themes. For example, Minty Zaki has green hair; Snowanna Rainbeau has a rainbow-coloured afro.
* ''WesternAnimation/TeenTitans'' has the green-haired (and skinned) Beast Boy and the violet-haired Raven as part of the main cast. In season 5, we're introduced to Kole, who has bright pink hair[[note]]Although an animation error in "Titans Together" would depict her with orange hair, which she had in her early concept art and in the original comics.[[/note]] Jinx is a villain example, with her hair also being pink.
* Sunil Nevla of ''WesternAnimation/LittlestPetShop2012'' is completely blue.
** Don't forget Zoe (purple/pink), her sister Gail [[and her male double]] (pink), Minka (also pink), Penny (light purple) and Sugar Sprinkles (orange, white and pink with sprinkles).
* Sincerity from ''WhatAboutMimi'' has pink hair.
* Five, the fifth most-dangerous human being on Earth, from ''WesternAnimation/GeneratorRex'' has pink hair.
* The Duke from ''WesternAnimation/{{Gawayn}}'' has naturally purple hair, his mother too.
* Played straight, Lampshaded, and Averted in PepperAnn. Pepper Ann dyes her hair green, in which her friends are indifferent about, causing Pepper Ann to call Milo out on having Blue hair, which he admits his hair is so naturally black it has a blue tint.
