I suggest a light blue color, a black color. A grey color, and a red color. And a half black half white color. I dont know, mix it. Alot of people in the Naruto show have weird skin color or strange fetures. I have a fan character and he happends to be light blue. So it would be cool if that color was in there so I could my character. Ginree in this game. But yeah, grey like Orochimaru. Black and white, like that Akatsuki dude. I dont know, just some ideas.
