Dogs do not see in black and white, but they are what we would call "color-blind," meaning they have only two color receptors (called cones) in their eyes, whereas most humans have three. ... So, technically, dogs are color-blind (in the most human sense of the word).

For dogs, their color vision is most similar to a human with red-green color blindness, although there are other differences. Dogs are less sensitive to variations in gray shades than humans are, as well as only about half as sensitive to changes in brightness. Dogs also tend to be nearsighted to varying degrees.

Blue-eyed dogs are rare. This distinctive look in one or both eyes is caused by a lack of pigment around the eye area, albinism, or a number of other genetic factors. Check out our article about how dogs get blue eyes, and the Dog Genetics website has more information about the genes that affect eye color.

While we can't ask dogs to read an eye chart or pick out colors, behavioral tests suggest that dogs see in shades of yellow and blue and lack the ability to see the range of colors from green to red. In other words, dogs see the colors of the world as basically yellow, blue, and gray.

Poor Color Vision and Animals Dogs, cats, mice, rats and rabbits have very poor color vision. In fact, they see mostly greys and some blues and yellows.

Answer: No, dogs are not colorblind in the sense that they see more than just black, white, and gray. ... “Human” reds, greens, and oranges are not distinguishable to dogs and instead appear somewhere on their yellow to blue spectrum.

Some Huskies have blue eyes due to a mutation in their genes which decreases the pigmentation in the eye. ... Not all Huskies have blue eyes though. Huskies can also have brown, bi-colored and parti-colored eyes, which makes them a unique breed when it comes to eye color.

In behavioral tests, cats don't seem to see the full range of colors that most humans do. Some experts believe cats' "color vision is limited to blue and grays, while others believe it is similar to dogs', but with less richness of hues and saturation of the colors," Ketring said.

Brown is the most common eye color for dogs, but many Siberian Huskies have striking blue eyes. They can also have brown eyes, one eye that is blue and one that is brown, or blue and brown coloring in both eyes. The color of their eyes is controlled by a rare gene that few dog breeds are believed to have.

By overlapping and mixing the spectrum of colors that the three human cones perceive, we are capable of seeing a wide variety of colors. In dogs, however, the two color receptors in the eyes perceive wavelengths of light that correspond to blue and yellow, meaning that dogs see only in combinations of blue and yellow.

White Siberian Huskies are actually quite rare. White is not one of the original color markings for the husky. Bright blue eyes fairly common among Siberian Huskies, but white is actually not technically a color. Certain Siberian Huskies have a recessive gene that makes their coat completely white.

Unlike most rodents, guinea pigs -- also called cavies because of their scientific name, Cavia porcellus -- do see colors. They are not color-blind; they see most colors accurately. They also rely on their other senses, such as hearing and touch, which are more developed.

Your Maltese pup is color blind and can only see varying shades of black and white. Also did you know they are nearsighted and rely more on their noses than on their eyes.

Elk don't have a red cone like humans, so the upper end of the color spectrum appears yellowish to elk. They aren't color blind, but they don't see color the way we do. ... Deer are essentially red-green colorblind like some humans. Their color vision is limited to the short (blue) and middle (green) wavelength colors.

As in white cats, the genes responsible for coat color, eye, and ear health are not causally linked, so white and albino dogs are not necessarily more likely to be born blind or deaf. However, a rare genetic combination, known as “double merle,” does carry inherent health risks.

Human eyes have three types of cones that can identify combinations of red, blue, and green. Dogs possess only two types of cones and can only discern blue and yellow - this limited color perception is called dichromatic vision.

Are they blind? They are not blind by nature, but pink-eyed rats do have a harder time seeing than ruby or black-eyed rats.
