Dog vision is very different from human vision. Dogs see the world in fewer hues than we do, but this doesn’t mean our canine companions are completely colorblind. But even if dogs’ visual worlds are not as clear or as colorful as ours, their ability to see motion is superior. 

What colors can dogs see?

The human eye works thanks to three kinds of color-detecting cells called cones. By comparing the way each of these cones is stimulated by incoming visible light, our brains distinguish red wavelengths from green wavelengths and blue wavelengths from yellow wavelengths. Dogs’ eyes, like those of most other mammals, contain just two kinds of cones. These enable their brains to distinguish blue from yellow, but not red from green.
