red light, green light, deers and dogs
For hunting, people suggest using red or green lights because deer can't see them right? Well, after doing research, yes deer cannot see green and red as we do and can also see a little bit of UV light. Dogs also have dichromatic vision and they too don't see red and green as we do. Ever shine a red or green light in front of a dog? My dogs go crazy and attack the light. This confuses me. What exactly do they see red and green light as and can people be sure that deer can't see what the dogs do?
