When I hunt the late Idaho mule deer season in the snow, I wear all white clothes, a white hat, white face paint, and even cover my backpack with white. The only dark things are my boots, my binoculars, my bow, and my eyes. I've always thought an all-white bow would be perfect for the late hunt.
Even during the elk season, if you look around and kind of squint your eyes, lots of the branches and small saplings look almost white.
