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 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 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 in the latest episode with Patti and Selma. 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
In Gargoyles, 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 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.
Except the stuffed one in the museum at the end of the chariot race, which is 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. 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.
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.)
Ever heard of Cape Verde?
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.
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 Total Drama World Tour, 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 Ka Blam, 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 Perky Goth alternate identity Lacey Shadows
Tasumi from The Replacements 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 a brunette.
On Pinky Dinky Doo, 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 Lady Lovely Locks, the eponymous character's eponymous locks are blonde with purple and pink highlights.
Many of the bird characters on 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 My Little Pony (including Friendship is Magic) have wildly varying colors of coats and manes, almost none of which are possible in real life. This includes Rainbow Dash, 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 Hi Hi Puffy Amiyumi, 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 two actual people, both of whom*
