I have worn blaze orange for over fifty years during hunting season. Animals are not afraid of the color nor do they see it well. Most all animals see everything in black and white for the most part -- sort of like a black and white photograph. (Over simplified a bit, but that is the gist of it).
Deer have walked up to within 10 feet of me without seeing me so long as I didn't move. I have seen full camo clothed hunters go the whole season without seeing any deer primarily because they don't know how to break up their silohuettes or how to stand still.
In sum: blaze orange gives an increased level of safety from other hunters, but of course it is not fool proof. Blaze orange does not alarm the prey.
Cogito, ergo armatum sum
