Dogs do not have trichromatic vision that allows them to see a wide range of colors so what colors can dogs see is very important to know. All Dogs have dichromatic vision which allows them to perceive fewer colors like shades of blue and violet clearly, able to distinguish yellow and lighter shades of these colors, and not able to see greens and reds but may appear as shades of gray and brown to them. Dogs rely on other senses like hearing smell to understand their environment better.
Dogs cannot see colors as humans do. Color differentiation can be possible due to cones and motion with different light levels can be detected through the retina. The two types of cones (dichromatic cones) help to discern shades of colors not actual colors as trichromatic cones do. It can be assumed that dogs are red-green color blind.

What is meant by color blindness in dogs and humans?
Dogs see like humans but the science behind dog vision they can’t see red, green, blue and orange color. These colors appear in shades of yellow and brown like color blindness in humans. In color blindness humans are not able to see red, green and blue color; only shades appear that are quite similar to dog vision.
Dog vision compared to humans
Based on genetic factors, dichromats have two cones and are able to represent their visible gamut and trichromatic cones in humans have three types of photoreceptors that are most sensitive to long, short and medium wavelengths.
The amount of rods in the eye is higher in dogs which helps to identify objects in the dark and also differentiate moving objects at a fast rate. The dogs may get distracted from a far distance like a bird flying from 40 meters and bark at him.

Different color toys fascinate dogs
The blue color toys stand out as purple for your canine friend and dog may find difficulty to distinguish red or green balls on grass. It says that blue and yellow combinations are more attractive and will be prominent to the dogs.
Do dogs perceive colors like humans?
No, dogs do not see all colors like humans do. They are not able to see all spectrum of colors, dogs rely on combinations of senses to interact like smell, hearing, and movement detection. Dogs see almost all colors except red-green appears only in shades. These colors appear to dogs as a combination of brown and yellowish.
Why do dogs not see all colors?
The color spectrum of cones in dogs is limited to shades of gray, yellow, brown and blue. It is called dichromatic vision similar to red-green color blindness in human special cases. Dogs rely on their senses of smell, hearing, and sight. Dogs spot prey and detect movement in low light conditions. The eyes rod cells respond against detecting motion and light both in animals and humans. Dogs do not see specific colors due to two types of color detecting cones that are not able to detect a few bright colors: red, green and sometimes blue.
What colors can dogs see more clearly?
The red-green perception of color blindness is considered abnormal in color detecting molecules. It is all due to cones in the retina, the human eye consists of retina lining within the eye that is able to capture incoming photons and transmit them along neural pathways, convert light into electrical signals for the brain to perceive a visual image. In some people these photoreceptors are missing that won’t be able to detect certain wavelengths and called color blindness.
In animals especially in dogs the same phenomena of photoreceptors would recognize and result in dogs not seeing some specific colors. Red-green makes them appear gray and brown to them.
What is the theory of Judy for dog vision?
Dogs can see only shades of black and white according to Will Judy, a dog fancier and a writer who also claims that dogs have a poor vision. He wrote manually in 1937 in his book “Training the Dog” explaining how dogs see shades and outlines highlighted of black and gray.

What is a common myth about dogs’ sight?
Dogs can’t see black and white it is a common myth, dogs can see a range of colors. Only red-green cones limit their ability to see exact shades but shades of gray brownish appear.
Do dogs have better night vision?
Humans see a wide spectrum of colors and dogs mainly see the world in shades of yellow, brown and blue and also have better night vision, detect things from far and analyze motion better than humans.
Why is it necessary to know what colors dogs see?
Knowing which colors dogs better perceive helps owners to choose toys, training instruments, playing objects they interact with as they will respond more cheerfully to colors like blue and yellow. Moreover dogs rely much more on their sense of smell to understand things better as they are mostly used for navigation.
Are all dogs hypoallergenic and others vision the same?
Yes most dogs have similar sight qualities but differences may occur based on age, eye health and other genetic factors.
Conclusion
It is very important to know what colors dogs can see. This will help to choose a dog gaming toys, training objects and to develop the dog’s behavior with the owner. Dogs can see almost all colors but red-green color does not appear more clear to dogs these colors appear in the shades of brown and yellowish. The colors like blue purple and yellow fascinate most to the dogs. As the dogs have dichromatic vision only have two types of cones, those limited to few colors as compared to humans, the people which have color blindness.
