Well, you only have 47 colors.
That's not bad that you don't have much, but more shades of standard colors would make it more useful. Especially green. Just add stuff like dark shades, and light. They will help with your color set.
Colorsets and playertypes are the same to me, they both suck, and they all suck just the same.
They don't suck, they help with making more realism with the game, or help you fantasize it.
But it's your opinion.
