Ahh, yes. My character is grayish and white. The reason why is because I don't like my characters began neon, blue, purple, or pink, etc. Though I have nothing against those colors, except for pink. I hate pink. Probably, people making their characters gray/white/black is because they want to look realistic. Sure, I want to look realistic but I put dark bat wings on my charrie. x3
And what Tariri said before me - I agree with her. Sometimes, they just want to make their characters look dark and seem like they had a horrible past. So...yeah. I have nothing wrong with this, just pointing it out.
