• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

Blue, purple, green, no hair dye required.

"And for some reason, I got blue hair. You gotta have blue hair."
Strong Bad (describing his Anime counterpart Stinkoman), Homestar Runner, "Japanese cartoon"

There are plenty of ways for characters to be differentiated from each other, but one of normally limited utility is hair color. Human hair has a limited amount of variation after all, even less if you want everyone on a half hour show once a week to be easily distinguished. Thus, this Trope was born, so that artists could have the full spectrum of color to utilize. It's so common that it's mostly considered an Acceptable Break From Reality now.

More than most media, Anime characters often have You Gotta Have Blue Hair. This started with Manga series that used distinctive colors on the covers to make characters stand out, as they all had either dark or light hair in the actual black and white pictures; Anime just brought it to the screen.

There are several reasons why artists do this. The first, as noted, is to help distinguish characters from each other, similar to the reasoning behind Anime Hair. It may be done to indicate character personality, such as an Emotionless Girl with blue or white hair. It may be done to indicate uniqueness from the rest of the cast if they are the only one with their hair color. Or, it may be done just to suit the artist's taste for variety.

This trope is not for hair colors that are impossible, but standing in for a plausible shade; that's Hair Color Dissonance. When the hair color is realistic but is not justified by the setting, that's Implausible Hair Color.

See also Mukokuseki and Amazing Technicolor Population. For characters with impossible hair styles, see the Anime Hair Trope.

Shy Blue-Haired Girl is a Sub-Trope that is about blue-haired girls specifically. Same thing for Rose-Haired Girl and pink-haired girls, as well as White-Haired Pretty Girl and White-Haired Pretty Boy. Elemental Hair can often overlap.

Sub-Trope of Hair Colors. For hair which is depicted as an odd color, but which is supposed to be a normal color (e.g., powder blue standing in for grey), see Hair Color Dissonance.

Examples of You Gotta Have Blue Hair include:

Real Life

  • The celebrated "Glowing Green Monkeys", who were created by gene-splicing lab monkeys with bioluminescent sea creatures. Their hair only glow under fluorescent light, however, and look more of a dull greenish-brown under normal conditions.
