An all black bow won't hurt anything unless it was high gloss paint, otherwise a bow is just that a bow, skinny limbs and a quiver. Its not a big blob. On the other hand I camo my bow just because I think it looks better and its neat looking, I don't camo it to hide it from the deer unless it was some bright color. I use oak leaves and non removable camo spray paint and make patterns on my recurve with them! Its allot of fun!
