Many people have been misled to believe that their canine friend is completely colorblind, when in fact, they see more than black and white or grays. However, dogs do not see colors the way humans do, which is why the theory came about that they are colorblind. The color range that dogs see is limited, but they can see certain colors; so therefore, when you buy certain toys for your dogs, when you know the colors they can see, you can be sure to buy them in these colors.
So What Colors Can My Dog See?
Your dog sees mostly blues, yellows, and grays with reds, greens, and orange typically not being distinguishable to your pooch and may appear more blue, yellow, or dark gray. The retina in your dog's eyes is different from human retinas in that they contain two different types of photoreceptors, cones, and rods. Human eyes contain several types of cones, but canines have more rods and have no fovea, which is what helps with the vivid image colors that humans see.
This means that your dog has excellent night vision that is far superior to humans because their motion detectors are much keener than that of humans.
If you were to throw an orange ball or Frisbee on the green-colored grass, your dog may see it as yellow on yellow, but they can easily catch it because of the great motion detection that they have. If you want your dog to see the colors you see, then you would want to buy him blue or yellow toys, but if your furniture is green, he or she may see it as a yellow or blue. Remember, your dog only has two cones in each eye, while you have several, so his view of colors is very limited and not as keen as humans.
Colorblind indicates that the dog sees no color, which is not true. A person that is completely colorblind can only see shades of gray, similar to watching a movie in black and white, but your dog can see some colors. Earth tones are typically seen by dogs more in a gray fashion, so if you have brown carpeting, your dog does not see the brown, but more of a brown-gray. If you have green carpet, it may look yellow to your dog.
