Dog Color Receptors
Some humans, about 8 percent of men and 0.5 percent of women, are similarly red-green color-blind. It turns out that dogs possess two types of color-sensing receptors, called cones, in their retinas. Are dogs colorblind? We spoke with a vet to break down the myth of color blindness in dogs and explain how pups really see the world.
The idea that dogs only see the world in black, white and shades of gray is a common misconception. What's true, though, is that like most mammals, dogs only have two types of color receptors. What Is Color Blindness? Color blindness in dogs and humans doesn't mean that you see in black and white.

Color blindness describes an inability to differentiate between colors or to see certain colors at all. This condition stems from an abnormality in the color. 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.
So instead of bright red roses, dogs likely see yellowish brown petals, and lively green grass looks more dehydrated and dead. However, dogs possess only two main types of color sensing receptors (cones), which means their vision is classified as dichromatic and limits their ability to detect different wavelengths of light. This dichromatic vision limits the colors they can see.

Dogs primarily perceive the world in blue, yellow, and hints of gray. Dogs can see two main colors: blue and yellow. Their color vision is less extensive than humans due to having only two types of color receptors.
They also see various shades of gray. Key Takeaways Dogs have two types of color receptors, primarily perceiving blues and yellows, and cannot effectively perceive red or green. Dogs compensate for their limited color vision with superior visual.

Dogs experience the world in ways that are both similar to and different from humans. While humans enjoy a rich spectrum of colors thanks to our trichromatic vision, dogs possess what is known as dichromatic vision. This means they have two types of color receptors (cones) in their eyes, limiting their color perception compared to humans.
What colors can dogs not see properly? Dogs have difficulty distinguishing between red and green, as these colors appear as varying shades of gray to them. How do dogs see colors compared to humans? Unlike humans who have three types of color receptors, dogs only have two, leading to a narrower color spectrum with a focus on blues and yellows. Dogs are dichromatic, which means they have two types of color receptors in their eyes, compared to humans who are trichromatic and have three types of color receptors.
This means that dogs see fewer colors than humans do. They primarily see shades of blue and yellow, and have difficulty distinguishing between red and green.
