Yea, was homework for my photoshop class, we were supposed to take a picture, make it black and white, then airbrush our own colors to it. in fact my "Avatar" picture is the one i photoshopped, if you wanted to compare hehe.
The chins have changed colors without my help anyway, they used to be both a gray with dark tips, now ones solid grey and the other is pretty much all black. The black one is most people's favorite because he has the white rings around the ears, and he has "eyebrows" because the fur above the eyes is a lighter shade than the rest of him
