- Two cases in Shikkoku No Sharnoth, though one is a subversion. Viola dyes her hair the purplish shade that it is, but Claudia's hair appears to be naturally green. However, she's an extremely minor character and may be dying it as well.
- Aoba in DRAMAtical Murder. He was born with white hair and has it in a Bad Ending
- In Lads In Distress Princess Charming has pink hair, Nicholl has blue hair, and Prince Snow has white hair. Can be handwaved by the magic inherent in the universe.
- 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 and later revealed to be dyed. 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.
- The school nurse, on the other hand, has light indigo hair.
- Miou and Miku in A Profile have blue and purple hair respectively. However, since Miku's hair is referred to as black, it's likely that both of their hair colors are not what we see.
- Most of the characters of Dangan Ronpa have oddly colored hair. Although a few of them are mentioned to have dyed it, and the blonds could just be of mixed heritage, one character has been seen with purple hair in her child photo along with her father whose hair is also purple.
- The dragon's hair in Dra Koi is bright pink and the protagonist has white hair.
- Higurashi: When They Cry: Hinamizawa seems to run off this, with each family having a weird hair colour; the Sonozaki women (Mion, Shion, Akane) have mint-green hair, the Furude women (Rika and her mother) have various shades of blue; Rika's mother has a darker shade, closer to black; Hanyuu, Rika's ancient relative, has lilac hair, Rena has orange-brown hair (which could be auburn, or ginger, but either way is unusual considering the game is set in Japan), and all of the Houjou family (including extended family) are blondes (a real-life hair colour, but like Rena's, it's still unusual given the setting).
- Rina has bubblegum pink hair, Irie has Rena's colour, Takano has Satoko's, and Chie-sensei has a shade that's even bluer than Rika's.
- In Hatoful Boyfriend the majority of characters are birds, but they have noncanon moe anthromorphizations who sometimes have unusual hair colors. In Ryouta's and Anghel's cases, blue and teal respectively, it's probably a more high-contrast version of their actual plumage, which is sort of blue-gray. Nageki's green hair may be a reference to the blue-green ring around his eyes. But two white doves are shown as humans with pale blue hair.
- In the Corpse Party Fan Sequels D2: Depths of Despair and Fatal Operation, Seiko has dyed her normally brown hair green. She tells the others she did this after losing a bet, but doesn't seem to mind.
- Even though the 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, Vera, Redd, or Lisa Basil (metallic blue, pink, dark blue, purple, and electric blue, respectively). While Redd and April could've dyed theirs, and Lisa's could just be part of her gimmick, Franziska's and Vera'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.
- Fate/stay night especially loves characters with purple and blue hair. The human characters include Shinji (blue) and his sister Sakura (purple), and their father also sported blue hair. Four of the seven servants also have hairstyles in varying hues of blue (Lancer, Assassin) and purple (Caster, Rider). And yet, only Saber's blonde hair ever gets commented on by other characters, usually when they're discussing how much she sticks out as an obvious foreigner in town.
- In Invisible Apartment, Kacey changes her hair colour to help disguise herself, but doesn't stick to natural shades. She starts the first game with purple hair, but has gone green by the end of it. (The prequel and sequel show her with black and blonde hair, though.)
- In Strawberry Vinegar, Rie and her father have bright pink hair, while her mother's is bright orange.
