RE: Deer cannot see orange.
they say that deer cannot see orange but Can see the ultraviolet light that is put out by it. Basically they can see the light bouncing off it.
Why do you spot more deer than your buddys? you answered it yourself, because you dont move. If you are still and they see you then they really don't know what you are, so they go on with their business, if you move, now your a threat!
