I agree with Jerry J. Dark dull colors are plenty good enough. In any event I'd avoid RIT for wool. For one thing, you're supposed to use boiling water, or close to it, which could cause shrinkage. For another thing, it's full of the kind of "laundry brighteners" that supposedly are highly visible to deer in low light. You can buy really fat permanent markers, which I've used with good success. But camo is overrated; good but far from essential. Different dark dull colors for top, bottom, hat, have never revealed me to game, includuing turkeys, deer, bear, elk, so long I'm in the shade and not moving.
