You might have heard the common myth that dogs see the world in black and white. But the truth is they can distinguish certain colors—just not the rich rainbow that we know. Studies suggest dogs best see shades of yellow, grey, and blue. An approximation of the range of colors dogs can see.
Dogs are not color blind, but they do see fewer colors than humans. The brightest colors in a dog's world are blue and yellow, making these the best choice when it comes to choosing a toy for your pup.
Research leads us to believe that dogs see the world through a unique color spectrum. Yellow and blue are dominant colors in dog color vision. Blue, blue-green, and violet look like varying shades of blue. Shades of red and green probably look more like browns and grayscale to a dog.
Dogs do see colors, but the colors are neither as rich nor as many as those seen by humans. Dogs may see green, yellow, and orange as yellowish, and violet and blue as blue. The color red is more difficult for dogs to see.
Dogs can only see blue, yellow, and some shades of gray. See the color chart below for an approximate idea of what colors dogs see best. Dogs would see a rainbow as dark yellow (sort of brownish), light yellow, gray, light blue, and dark blue. Dogs don't see red, purple (violet), or orange like we do.
Dogs absolutely can see TV, and many seem to enjoy it. There are a number of features about television shows that dogs find attractive. Some of these are visual, such as motion, while others relate to the sounds coming from the TV. Dog eyes are very different from human eyes, so they see things on TV differently.

If playing indoors, you can essentially choose any colour of toy that your dog can see – like blue, yellow, or purple. Now you know the answer to the question of “what is your dog's favourite colour?” — it's blue!
Dogs can see color, but only in shades of blue and yellow. Because dogs can only see two colors, they have dichromatic vision. They can also see shades of gray. Colors such as red, orange, and green are out of a dog's color spectrum, so these colors are not visible to dogs.
Obviously, his stronger sense of smell is useful, but it's also because dogs can see movement and light in the dark, and other low-light situations, better than humans. They are assisted by the high number of light-sensitive rods within the retina of their eyes. Rods collect dim light, supporting better night vision.
You might notice this while playing with your dog — "dogs are not good at seeing a bright red or orange ball on green grass but they are good at seeing blue from all other colors," Neitz says.
Dogs see like a color-blind human. Many people think that a person who is red / green color blind cannot see any color, but there are variations of color blindness. Most people have vision that is trichromatic (three-color variations). People who are red / green color blind are dichromatic (two color variations).
Red, orange and yellow are stimulating to humans but blue and violet are calming. Toss your dog two toys — one yellow and one blue — and see if the yellow toy inspires a more energetic playtime. Or the next time your dog gets anxious from a thunderstorm or noisy fireworks, try exposing him to soothing colors.
According to the Sleep Foundation, dogs, like humans, have circadian rhythms that are influenced by light. It's easier for them to sleep if it's dark, or at least dim. Can dogs be scared of the dark? It's not common.
Green is a very calming color and has been known to help reduce anxiety in dogs. Yellow is also a great calming color, but it is important to use a light shade of yellow so that it does not appear too bright or overwhelming to dogs.
However, dogs are also often afraid of things that are in no way dangerous to them. In fact, some of the most common dog fears include loud noises, loud people, other dogs and changes in weather such as a thunderstorm, says Dr. Denise Petryk, a technical services veterinarian in Canada.
Dogs choose mostly intense, animal-derived smells, such as feces or carcasses, so there is a need to differentiate between canine and human smell preferences.
Many dogs have sound phobias to loud noises like fireworks, thunderstorms, gunshots, and firecrackers. There is even research that suggests noise phobias can be inherited. According to Dr. Klein, herding breeds are particularly sensitive to noise phobias, perhaps because they are so attuned to their environment.
Cynophobia is the overwhelming fear of dogs. People with this anxiety disorder feel intense fear and anxiety when they think about, see or encounter a dog. In severe cases, this phobia can cause people to avoid places where dogs might be.
Most typically, we find dogs that are afraid of loud noises, such as thunderstorms and fireworks, but also they can become fearful of children, men, riding in cars, going down stairs and such, or esoteric things, such as butterflies or flickering shadows.
In reality, you're most likely going to want to choose colors that have a calming and soothing effect. For those, I'd recommend a lighter shade of blue, something more like a pastel hue. This is more likely to encourage your pet to remain relaxed. You might think that white would also be a good color, but not always!
We have receptors for the wavelengths that create red, green and blue – which enable us to see all combinations of those colors. Dogs only have two cones, for blue and yellow -- which is why the dog's rainbow above looks quite a bit duller than ours.
