I’m color blind, but it’s weird. I have track and helped track more wooded deer than I care too, but it’s part of the game. When I’m following a blood trail, I usually don’t see blood as red, it’s more of a dark wet spot on the ground, same with snow cover. With snow it looks like someone sprinkled pepper along the trail if it's just drops or spray. Now if I reach down and touch that spot with my bare hand or finger then look at my finger I see red, much like I cut that finger. As I said it’s weird, and I have to look and concentrate a lot harder than some one who isn’t color blind, but I have got it done.
