The research I' ve seen says deer vision is comparable to a human who is red-green colorblind , and they see mostly blue , yellow , and gray . They see blue best , which would make jeans a poor choice for hunting . They also have little or no depth perception because of where their eyes are mounted on their skull . This might explain why they have trouble seeing you when you don' t move . It does , however , give them a visual field of view that allows them to see trouble coming from any direction without turning their heads . I was intrigued by these findings since it suggests that nearly anything which breaks up your outline could be considered effective camo . I once saw a b&w photo of a guy in a hawaiian shirt who nearly disappeared into the background simply because of the pattern on the shirt . If he had been hunting at the time a deer would never have noticed him . The color photo showed his shirt was colored in reds , yellows , and greens . I' ll bet the folks at Mossy Oak would hate for that to be common knowledge ! [>:]
