What is Color Blindness?

The English scientist John Dalton made the first studies on congenital color blindness at the end of the 18th century. These works emerged as a result of his brother’s inability to see certain colors, and his mixing of red with green and pink with blue. Red-green color blindness is the most common color deficiency in humans. Red-green color blindness is seen in 8% of men and 0.5% of women, who are descended from Northern Europe. Color blindness is a disorder that occurs in the molecules in the retina, called cones, that perceive colors. The retina converts light into electrical signals, and these signals are transmitted to the brain by the optic nerves and visuals are created. Color blindness can be congenital as well as later with a disease or injury. In dogs, this situation does not come from a deficiency. This is how dogs see it. Cone cells in the eye provide daytime vision and form the perception of color. It provides night vision in cells called rods and provides edge-to-edge, peripheral vision. Each cone cell perceives the wavelength of light. Humans have three cone cells and can usually see the full spectrum of light. Dogs have only two cone cells. These three cone cells in humans and some other primate species are called trichromatic. Dogs and are dichromatic as they only have two species.

What Colors Do Dogs See?

The two cone cells in the eyes of dogs enable them to perceive only the color blue and yellow. Green and red colors are absent in dogs. At this point, “How do dogs see colors?” The answer to the question is that dogs can see the color blue and yellow. There is no change in light perception. At this point, there are yellow, brown, gray and blue colors. Bright red colored toys are actually seen brown by dogs. For this reason, it is possible to say that the color perception of dogs is very close to people with green-red color blindness. As a result, dogs cannot distinguish between green and red colors.

What Do Colors Mean to Dogs?

“Do dogs see color?” After answering the question, the important thing is to understand what these colors mean to them. Many people buy brightly colored toys, collars or beds for their dogs. Although these are of interest to humans, there are doubts about their interest in dogs. Having a colorful rainbow in a toy does not provide a full feast of colors for dogs, it does not provide the expected visual effect. Marketers and graphic designers know that people love bright red and orange. However, these colors have no meaning for dogs because they cannot perceive these colors. Dog trainers or enthusiasts make their choices based on the color perception of dogs when choosing products for dogs. Professional dog trainers are usually colored blue and yellow. Dogs can find frisbees and balls in these colors much faster. If you look carefully, it is possible to see that dogs love tennis balls more than other toys and are interested in them for a longer period of time. The biggest reason for this is not because they can see green. It is because they can distinguish yellow and blue from green.
