I wear full blaze orange head to toe while white tail deer hunting and have shot over 100 deer all in full blaze. as long as you know the wind and DONT MOVE you are good. I have never had a deer see me because of orange it was movement or scent and my fault and i knew it the joys of being busted. if you sit in a tree long enough you learn alot. I have had deer stare at me 10 to 15 feet away trying to figure out what i was a few times only thing i can say is you will never win a starring contest with a deer. I do think cammo would be a good idea when bow hunting or hunting close to the game trails as i never sit on a trail always off to the side as far as I can and still be able to get a clear shot. but deer that travel the same trails know what is suposed to be there and what is not.
