Guys, not ALL the characters' names HAVE to relate to color. As seen in the show, color names became a cultural custom after a certain point in the past. People like Ozpin, Goodwitch, Ironwood, they don't have to have color names, because they could have been born before color names became a custom. But characters around say, the Beacon students' age - 17 or younger - definitely would have a color name. And every character of that age range does.
