Myth: Deer can’t see colors. Here are the facts:
Can white-tailed deer see colors? Hunter orange, or blaze orange, is a common color often associated with the myth of deer not being able to see colors. However, just because deer do not respond to hunter orange the same way humans do, doesn’t mean that they can’t see them. Florescent orange glows to humans, yet deer seem to have a hard time picking it out in the whitetail woods.
I have a British Lab and I’ve noticed a drastic difference in her ability to see the color red when playing fetch. I purchased a small red toy for her and if I throw it in the leaves or an area that it doesn’t stand out against a different color background, she has trouble finding it until she catches it’s scent. She’s got a great nose on her, but the color red doesn’t stand out against similar colors. We’ve since retired this toy and now use a different color and she’s able to see it without issue. This observation allows me to better understand how deer perceive colors as well.
Research dating back to the 1980’s proves that deer can in fact see some colors. More recent research by the University of Washington and the University of Georgia began to reveal some very specific facts about what deer see. By dissecting a whitetail’s eyeball and putting it under a high-powered microscope, scientists were able to analyze the color vision in whitetails by looking at the rods and cones on the retina.
Rods collect light and cones interpret colors. By analyzing the specific kinds of cones in the deer’s eye, scientists discovered that deer do not see the red end of the spectrum visible to humans, but they see the blue end significantly better than we do. Colors like orange and red are subdued, but greens and blues are very visible to deer.
Humans have a UV filter on our eyes, which blocks out much of the blue light that can harm our eyesight over a lifetime. Because deer live much shorter lives, they do not need this filter. Between the lack of a UV filter and the number of cones that interpret blue light, a whitetail deer can see blue approximately 20 times better than humans can.
