I often mix patterns, one makers pants, anothers top. That gives me a really bold shape and color change change. As noted, many of the designer patterns tend to meld into single colors at any distance. Much of the camo industry seems to be money making.
In the spring, once things green out, for turkeys I often hunt in GI woodland with no regrets. In the fall, or early spring, I keep to grays and browns.
Big believer in gloves (your hands move alot) and broad brimmed hats, which tend to break up the characteristic little head and square shoulders of an upright human.
One stupid thing, I absolutely hate camo clothes and a flourescent orange hat. Unfortunately sometimes required (by law).
