Yes, I did. As she said, the color white is cooler & more reflective of the heat. Pastels can be used as she has done. Down here in Fl. one would do best to keep the hives white as we get so hot & have so much sun. However, colors can help the bees find their hive & keep them from drifting as Mindy says. A common practice down here is to paint a different colored dot on each hive to achieve the same purpose. Or you can use a dot here & a dash there & an x there & whatever your little heart desires. The bees will more easily locate their hive by the mark you put on it. This is especially important in commercial operations where you are moving them to different nectar locations. If your house got moved in the middle of the night & you awoke looking for your home after going out for breakfast you would be thankful for a familiar "sign" to tell you when you have the correct house so you don't try to walk in the front door of your neighbors house.
And with bees, you will be promptly ejected if not killed.
