What colors can DEER not see
For all of you 2014 owners, you better install some blue Aux lights soon 🙂
As per Google;
Deer do not see well in the longer and middle wavelengths (oranges, greens, yellows, browns and reds) in the visible color spectrum. These colors appear in shades of gray or yellow. Where they see very well is in the low wavelengths — the BLUE range.
Deer eyes only have two photopigment types, giving them dichromatic color vision. Scientists believe that deer can primarily see short-wavelength blue light, and moderate-wavelength light that they probably perceive as something between red and green.
Deer are essentially red-green color blind like some humans. Their color vision is limited to the short [blue] and middle [green] wavelength colors. As a result, deer likely can distinguish blue from red, but not green from red, or orange from red."
The results showed that deer are red-green color blind. ... Deer also can see UV light in low light hours. It was suggested in the study that, during early morning or late evening, hunters wearing UV brightening fabric cleaners might actually glow blue to the eyes of the deer.
Deer sense colors toward the violet end of the spectrum, so they can see blues and probably even ultraviolet (UV) light. Deer show a slight sensitivity to yellow, but tests indicate that green, orange, and red appear to them as shades of gray. Exactly how well deer see UV light is debatable.
