In my opinion.
Camo makes little difference. If you have to rely on camo to break up your outline in the country we hunt antelope in you are already screwed. Antelope eyesight is so good that eliminating line-of-sight and looking at them through the grass and sage, not over it, will allow you to slip in undetected. I wear tough pants with knee pads and leather gloves. I crouch and walk until about to breach line-of-sight. Then crawl on my hands and knees until the cover is too short, then crawl on my belly until I run out of cover. From there, I only move to set up for the shot when they are not looking in my direction. I don't guess it would matter if I was wearing hot pink or zombie green. Eliminating direct line-of-sight is the best way to defeat a pronghorn's threat detection system. Of course, standard wind discipline applies.
Extreme skyline discipline is required. They will pick you out in an instant from virtually any distance if you silhouette yourself.
