That may be true, but in 21 years of hunting deer...primarily in blue jeans, and with a success rate of over 99%, I don't think they CARE when they DO see it. I guess I don't overthink the idea of hunting pants....I either wear older blue jeans, a pear of heavy duty woodland camo cargo pants, or coveralls, dependant on the weather. To this day, though, I don't believe my pants have made or broke a huntDeer CAN see the color blue.
