Physical attributes such as hair, face, and eyes are the initial factors one notices in someone. They are like the first impression one would have, and sometimes we even remember someone by that attribute rather than their real name. People often say, "Oh, the one with red hair, I have seen him." The point is people do notice, but once someone knows the person for real, the outside beauty barely matters. The thing is, in the anime world, sometimes characters are remembered by these attributes. For instance, you might have heard people saying, "Oh, the character with yellow hairs, I like how he slays with thunder." Or "I am in love with the character with boar head-on." It is mainly with international fans who find it challenging to remember characters' names or maybe with people who saw an anime long ago. We would refer to a character more than the name by describing a particular attribute it carries. Anime characters comprise various hair colors like white, yellow, red, brown, green, and even pink.
