"A common misconception among pet owners is that dogs are colorblind. In reality, dogs have dichromatic vision and can see most of the range of colors humans can see. Though they can’t distinguish colors in the 510 to 590 nanometers, or wavelengths, range—between green to orange. Other key functions in canine vision include seeing better in low light than humans can, and being able to see into the ultraviolet UVB spectrum. " Feline color perception is different than dogs but does have similar characteristics. Cat's vision is trichromatic, but they can’t see colors with as much precision as humans do. They also discern the blue and violet end of the spectrum better than the red end."
