RE: Color blind people going hunting?!?!?!?!
I have some color blindness of dull shades of green telling from brown. I can't see small spots of red on green. But I have normal, whatever that means, color sight in all other ranges. I do like to hunt deer in the snow to make it easier to see blood. However, I'm not ashamed to bring someone with who sees red on green better to help track.
I've heard the tip about using peroxide in a spray bottle to see the blood trail foam up before. I haven't had to use that since hearing it or the LED lights that supposedly help make the blood fluoresce. But it is good to share those things. We help each other out.
Above all else, safety first.
