RE: can deer see orange?
Heck, we can't even have words on our blaze! It has to be completely SOLID to be legal! That being said, I will wear a solid hat and a break up patterned coverall (orange), and I have had success during gun season as well. I shot my 7pt. at about 30 yards, and he was headed straight for me.
I don't know what they can and can't see, NO ONE may *really* know, but I think the biggest thing to remember is to stay still, they can very easily pick off a movement they don't recognize as "natural".
