Feileadh Mor tartan as camouflage?

No one seems to have mentioned that Deer and Elk are essentially red-green color blind. Their color vision is limited to the short blue and middle green wavelengths of colors. As a result, deer and elk can distinguish blue from red, but not green from red, or orange from red. You can hunt in blaze orange as deer and elk see this as gray or brown.
