I saw this picture today and am trying to figure it out. I don't know how a solid black cat can have a pink nose and toes, genetically speaking. Is he a smoke? Is he really black and white but the white only ended up on his bare skin?
My guess would be vitiligo, which can sometimes affect a cat's skin (nose, lips, paw pads) rather than the hair. If you scroll down on this page you'll see some examples of acrofacial vitiligo which look similar.
