blue hair
Hair that is colored blue.
Due to the subjective nature of color judgment and other factors (such as the lighting on the characters) there is an overlap between this tag, and the aqua hair tags. Due to blue often being the undertone used for black hair and white hair, there is an additional overlap with those tags too.
