Outdoor Paint Colors

Living near a water "dobbers Earth" are constantly building the nest on the porch. Wondering if a paint color could slow the flood of nest.

I am not sure of the painting, but I had a couple of apartment complex managers who swore by yellow bulbs for porch lights. There was nothing special, just that they have been colored yellow. I can not really say I thought they were effective, but to be in front of the floodplain of a stream, we do not seem to have mosquitoes or spiders accumulate around porch lights as houses neighbors who have used standard white.

green or blue
