I have known for about the last dozen years that I'm color blind enough to not pass the card test, though red green seems to be ok. After talking to an optometrist I found out that depending on the form of color blindness some can spot camo patterns normal color vision people couldn't. When hunting, depending on light, I sometimes find myself looking more for movement to spot deer than seeing through brush. I also pay alot more attention to sounds than I used to. A relative of mine is color blind as well but his is worse seeing greys instead of blues and such but he still hunts with no apparent problem. I am wondering how others that have color blindness handle their hunting in spotting game and tracking after the shot.
