In our mild Pacific climate (it rarely drops to zero or climbs above
90 degrees) many beekeepers think they get better yeilds using a dark
green or brown latex for the outside of the supers.  In addition, this
helps hide hives from prying eyes in remote outyards.  Never put anything
on the inside (except maybe beeswax & I don't know anyone who bothers
with that.
 
The darker paint helps the bees warm up faster in the cool of the morning.
