i've heard that blue is the worst thing you can wear while hunting, but i heard that for deer, so i don't know how it applies to other game.
around here, i hunt in desert bdu's, with thermals under them if it gets chilly. not necessarily for the camouflage but for the abundant pockets. i figure the camo can't hurt, anyway. i also have a set of greens for up north, and my boots are tan.
