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. Cheers..... Dave Pehling WSU Cooperative Extension [log in to unmask]
