Animals care about movement, not color.
Even turkeys don't care about blaze orange unless it moves, and they can see color. They see it move easier than some camo but movement is likely to get you busted either way.
The best camo available isn't one that looks good to people. Those patterns of leaves, sticks, brown, are noting but a man-shaped blob of brown to most animals. You need a pattern that breaks up the human shape by using dramatic contrast in larger areas. Scent Loc Vertigo and ASAT are good examples.
Otherwise, plaid shirts and blue jeans are as good as anything else.
You DO want your face and eyes hidden, and DO NOT make eye contact.
