I'm not so sure that it matters really - having some black around/on you, but it doesn't make me feel good, so I try to eliminate it. I had a reversible sweat jacket that was camo on one side and black on the other. Every time I wore it, I worried about if the deer could see the black on the inside of the hood that was visible. I don't think it made a difference, but decided to get rid of it since I couldn't get past it. I'd rather feel confident and worry about other things in the woods like "hey, what was that noise?" instead of "hey, what was that noise, god I really hope they can't see this black in my hood!"
