Why when you have white cat does he only sit on your dark clothes and vice-versa?

I have a white cat, he seems to ONLY sit on dark clothes, or if you have a dark outfit on.  When I'm wearing white shorts & a t-shirt, I can't BEG him to sit on my lap!I think it's spite.

I have a long-haired calico, mostly white, she ALWAYS does that!  And then my black cat....always on my lite colored throws and blankets!

But I love 'em anyway......:)same reason when you drop buttered toast it always falls buttered side down ...murphys lawHe does it because he can. That and you probably respond differently to the kitty when its about to leave a fur trail on your dark clothes.That's easy: he wants to stand out from his background!And if the air is especially full of static, just walking by the cat -  hair flings to you like a magnet.A cat does this to stand out to make sure it is noticed and not accidental trodden on when snoozing.cats enjoy leaving there mark on everything at least yours only leaves fur on everything. my cat has to scratch everything including my legs.
