Strut&Rut and Jeff, those are EXACTLY my thoughts. I base my camo purchases on what is the most difficult to see by the prey I intend to hunt. Deer see TOTALLY different than we do. I' m interested in fooling their eyes, not mine, despite all the marketing efforts of RealTree, Mossy Oak et al...

Strut&Rut posted very good info on how deer see. Here' s some more from the Sticks and Limbs site- http://www.bowhunting.net/sticks/how.html#tophow

If hunting humans ever becomes popular, I now know what patterns to consider buying

Thought I should add. I have an ASAT 3D suit that I wear over whatever the weather dictates for hunting deer. I also have Seclusion for turkey hunting, although ASAT works very well for them also.
