One of the most popular and common hair colors for people out there is brown. Although chocolate-colored locks are beautiful, they seem to be overrated, especially when it comes to anime characters. In recent years, most anime protagonists, whether a girl or a boy, have unique hair colors or highlights to make them more memorable. An example of this trend is Usagi from Sailor Moon, who sports golden hair, Nezuko from Demon Slayer, who has black hair with orange tips, and even Rem from Re: Zero, whose hair is blue.
