>>Color has more to do with sex, and food (prey/hunter) than warmth, 
otherwise polar bears would be black.

Yes and no. :))  Fun fact: it's not readily apparent but polar bears' 
skin is black for warmth.  If you shaved a polar bear you'd see black 
skin all over.  The fur hairs are special light pipes that 
efficiently bring the sun's radiation directly to the animal's skin.  
The hair is also hollow allowing the large animal to stay bouyant in 
water...  

Having said this, I have little opinion about bees' colors.  Very 
dark bees - as well as as lighter ones - can be found in the tropics 
and in temperate zones.
