Kat is the red head, gin is the one with purple hair and kurama is the one with black hair. and in reply to Kaze shi, he has four, the fourth is just hidden (it's mildly bent so it's not visible) and actually, Togashi-sama colored some of his artwork, kurama's hair was black, kuwa's was orange, yuu and hiei's was also black. It wasn't just the fact that manga is in black and white, although you will find things such as covers to chapters and the occasional chapter WILL be colored. But as stated, they changed his hair to red in the anime.

In the manga, Kurama's hair is black because there's no color to it besides black and white. And Kurama only has four fingers. I like how you colored it, and their outfits are pretty cute.

I give two thums up for the art, and a confused look for wut you wrote. So who's who?
