Do spiders usually have yellow bellies?

My spider has a yellow belly. Is this common? He's not really a "high white" spider. when I got him, I really liked how much yellow there was in his base coloration because, wanting to make bumble bees eventually, I thought this might make a good combo. Anyway, is this yellow common? Does it "brown out" like pastels tend to do?
