Dogs CAN see in colour: Scientists dispel the myth that canines can only see in black and white. There's a common misconception that dogs can only see in monochrome and use varying brightness levels to identify the outlines of items.

Human eyes contain three 'cones' that can distinguish between red, blue, yellow and green light making it possible to see the full colour spectrum, left. Dogs only have two cones, meaning they can't distinguish between red and green and see colours on a blue and yellow scale, right.

Previously, dog trainers would avoid using coloured objects when training pets to do certain tasks, but these findings could improve how animals are trained and what they are capable of learning. There's a common misconception that dogs can only see in monochrome and use brightness levels to see the outlines of items. Russian scientists have now proved not only do dogs have a limited colour range, they use this visual spectrum to distinguish between objects and select certain items.

Dogs, however, see colors in a way that’s different than the way humans do, which is why the theory came about that they are colorblind. Dogs see colors such as yellow, so its a good choice for dog toys. The color range that dogs see is limited, but they can see certain colors. So when buy certain toys for your dogs, when you know the colors they can see, you can be sure to get them in these colors.

However, its many fewer colors as compared to normal people do. To be more specific, instead of seeing the rainbow as ROYGBIV (red, orange, yellow, green, blue, indigo, and violet), dogs see a very dark gray, darker yellow (kind of brown, light yellow, gray, light blue, and dark blue. In other words, dogs only see the colors of the world as essentially gray, blue, and yellow.

But, they can see a variety of shades of blue, and can even tell between very closely related tones of gray that are not normally discernible to people. To put it simply, dogs can see in color; only that the colors that our four-legged friends see are not rich as what you and I usually see. The Reason Behind Your Dog’s Color Limitations: Our eyes and those of our pooches generally consist of cones, or special light catching cells that respond to color.

Neitz confirmed that dogs actually do see color, but many fewer colors than normal humans do. Instead of seeing the rainbow as violet, blue, blue-green, green, yellow, orange and red, dogs would see it as dark blue, light blue, gray, light yellow, darker yellow (sort of brown), and very dark gray. In other words, dogs see the colors of the world as basically yellow, blue and gray. They see the colors green, yellow and orange as yellowish, and they see violet and blue as blue. Blue-green is seen as a gray. You can see what the spectrum looks like to people and dogs below. One amusing or odd fact is that the most popular colors for dog toys today are red or safety orange (the bright orange red on traffic cones or safety vests). However red is difficult for dogs to see.

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.

Colorblind indicates that the dog sees no color, which is not true. A person who 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.

Yes, like us, our dogs can see in color. However, their perception of various colors is not exactly the same as it is for humans. As a matter of fact, dogs can’t distinguish between yellow, orange, red, or green.
