I dont but when I carry decoys and if I am carrying a bird back I will have a blaze orange flag showing. During our deer gun season I was in full blaze orange and had a flock of turkeys not 10 yards from me (I was on the ground), I just stayed still and they never got spooked or jumpy at all. Im no turkey biologist but I think they see color, otherwise I think it would be a law to wear blaze orange just like it is for deer. Im just glad turkeys can't smell, otherwise you'd never kill one.
