In fact, color camouflage, one of nature's favorite survival mechanisms, depends on the ability of the predator to distinguish colors. Dogs do not see black and white, they can distinguish colors, but not in the same way we do. "Dogs do have fewer color sensitive cone receptors in their retinas than their human counterparts," says Dr. Martin Goldstein, an integrative veterinarian and author of The Nature of Healing Animals. Dogs see like a color-blind human. Cats and dogs don't see as many colors but have a wider field of vision and see better at night. Although there has been a misconception that dogs are colorblind and can only see shades of grey, it is now well known that dogs can indeed see colors.

We now know a lot more about how dogs see the world than we did 10 years ago. The idea that dogs only see the world in black, white and shades of gray is a common misconception. We know this because humans have three types of photoreceptors in our eyes that transmit signals in the brain over color, while our furry friends have only two types of photoreceptors, which allow them to see differences in a certain range of colors. How cats see color is a long-standing topic of research and the results are pretty amazing. What dogs can see on the screen is also different to humans. For some time, many believed that canine vision was limited and that dogs were completely colorblind; however, a 1995 study published in the Journal of the American Veterinary Medical Association revealed that dog retinas possess many color-sensitive cones, and that dogs therefore can see in color.
