Dogs Are Not Color Blind But See a Different Spectrum

Contrary to popular belief, dogs do not see the world in black and white. They can actually perceive colors, but their spectrum is limited to yellows and blues. This means dogs cannot distinguish between red and green, similar to humans with red-green color blindness.

More detail

The myth that dogs only see in black and white dates back to the 1930s when a dog magazine publisher made the claim without scientific evidence. Modern research reveals that dogs are dichromatic, meaning they have two types of color-detecting cones in their retinas, while humans have three. Dogs can see yellow and blue clearly, but red appears as a dark brown or gray to them. This evolutionary adaptation makes sense since dogs are crepuscular hunters, most active at dawn and dusk when color vision matters less than detecting movement in low light. If you want your dog to easily spot their toys, choose blue and yellow ones.
