Yet they see the short wavelength colors very well. The trade off of having more rods and less cones is that they are not able to see color as well.

Deer have only green and blue, they are dichromatic.
What colors do deer see well. We can see all colors found in this word but there are some colors that cannot be seen by deer. These colors appear in shades of gray or yellow. Input from rods may also be used by deer to further discriminate colors.
Additionally, human eyes have uv filters, and deer eyes do not. Humans have red, green and blue cones. In addition, don't confuse uv light with infrared light.
Cohen deduced that, looking at the color spectrum, deer see blue colors best and red colors the worst. "color" is how we perceive. Deer see differently from humans.
And sometimes white color also. "with each research project that studies deer vision, we gather more and more data that gives us a better idea of how whitetails see. "deer see darker blues than we can see, and they see into the uv range, but i doubt what they see is glowing," said university of uga professor karl miller, who oversaw cohen's research.
Cohen found that deer see blue colors best and red colors the worst. Many deer spotters make the mistake of wearing camouflage that contains lots of white. What researchers have found is that deer can see colors, though they don't experience them in the same way we do.
Deer can see colors in brown, gray shades well than other colors. "blue jeans are much more vivid to a deer than blaze orange," said murphy. Research has shown deer to have photopigments that can detect colors in the blue and green range.
Deer are not color blind but their vision is different from ours. The yellows are somewhere in the middle. Where they see very well is in the low wavelengths — the blue range.
This is actually a mistake because those blots of white reflect all colors. What this means to a hunter is that you should avoid wearing anything blue. Deer do not see well in the longer and middle wavelengths (oranges, greens, yellows, browns and reds) in the visible color spectrum.
The high number of rods help them see very well at night. Deer can also see greens, yellows and uv light, but they can't differentiate color shades to that extent that humans can. It's not true that they only see in black.
Still, it's doubtful deer see uv colors the way we see objects glowing under black lights. Research by the university of georgia has found that deer eyes have many more rods and less cones relative to humans. Deer do not need to be able to see things clearly, they just need to know if there's a threat.
"blue jeans are much more vivid to a deer than blaze orange," said murphy. Without delving too much into the technicalities of nano meters, rods, and cones, it basically means that they can differentiate red from blue, but not from green or orange. Deer do not see the longer wavelengths, so they do not see much red.
Deer perceive colors differently from humans. To get us started, let's look at a few basics on deer color vision. Deer eyes are heavy on rods and light on cones, so whitetails and muleys move easily in the dark.
The human pupil is round in shape and the deer pupil has an oval shape. Orange is near the red end of the spectrum, so they do not see it well. After a brief training period, deer were tested on six different light wavelengths with varying intensities to establish what colors of light they can see.
They can pick out short (blue) and middle (green) wavelength colors, but they're less sensitive to long wavelength colors such as red and orange. Of course deer may not interpret colors in the same manner humans do, but it makes sense for deer to have sensitivities to blue and green colors. Recent research also shows that deer see some colors fairly well.
They see blues better than we do. Deer only have two cones, that is the types of photoreceptor that see color.
