I've been thinking about this heavily; particularly since getting turned onto saddle hunting... When using a stand, you're basically a blob suspended off the side of a tree from one cleary, horizontal platform (or two platforms in the case of a climber). In a stand, camo is used to make you blend in with other foliage behind you. The goal is to break up your outline. When saddle hunting though, and specifically in the case of one who leans, I believe your goal should be to look like an appendage of the tree itself. No longer should you try to blend in with what's behind you. But instead, capitalize on the tree you're actually attached to. Because of the upward angle created where your feet meet the trunk of the tree, and the girth of your legs, you'd be better served by "becoming a branch". Wear grey boots, grey pants, and a leafy top!
