Well, I guess, since black absorbes more light, the fur will become more warm. Predators, of course, will have a disadvantage of a black fur (easier to be spotted) so, they're white and have a fur wich is more thick.
Or am I responding to a question wich is a bit :crazy:?

Going to the other pole, you know polar bears are dark? Their skin anyway. Their fur is not actually white, but translucent, which assists in getting transmitted sunlight to the skin where it provides some degree of warming.

Nope. The fur conducts visible light to the skin where it is warmed, but the insulating effects of the fur and the fact that it is effectively 'white' make it a poor re-radiator of the accumulated heat.
