I realize this is kind of late, but I was wondering why KI didn't use a base color system ,so that your charater stays the same color from the start of the game. Instead, of the clothes having there own colors and have to paint them. Example, if the charater is fire, the clothes turn red.
That's not a bad idea. But either way, I have to dye my clothes, because I don't use just the school colors. My Balance wiz wears white and pink. You'll find that most of the clothes do actually start at school colors. Look in the bazaar, there's plenty there, and a lot of them give you the option of picking your colors.
