It is widely believed that dogs see in black and white, and for years, this idea was accepted as fact, although this is nothing more than a myth.
Multiple studies have shown the opposite regarding the colors that dogs can see, that go far beyond just black and white.
Do dogs see in colors?
To differentiate color, human eyes have three types of cones, which are red-detecting, green-detecting, and blue-detecting cones. Dogs, on the other hand, only have two types of cones in their eyes, which allow them to detect blue and yellow.
This limited color perception is called dichromatic vision, but dogs can indeed see color, but only in certain combinations. Their eyes have two cones that identify color, blue and yellow, unlike humans, which have three, red, green and blue.
While perfect vision for a person is 20/20, the typical vision of dogs is around 20/75. That means that what a person with normal vision can see clearly from 75 meters, the dog must be at 20 meters to see it the same way.

What colors can dogs see?
Since dogs do not have red-sensitive cones, their vision is comparable to that of someone with red-green color blindness. A human being with red-green color blindness will confuse shades of a certain color with another. For example, black could be perceived as multiple shades of red or bright green could be identified as yellow.
For dogs, it’s similar. Most of their worldview is grayish brown. A couple of examples are, a red rubber ball might look brown through a dog’s eyes or your pup’s favorite green dinosaur stuffed toy might appear yellowish to him.
Dogs can only see the colors yellow and blue-violet, and thus, they perceive red and orange as if they were shades of yellow and do not differentiate green from white or discriminate blue-green from gray.
