Human eyes have three types of cones that can identify combinations of red, blue, and green. Dogs possess only two types of cones and can only discern blue and yellow - this limited color perception is called dichromatic vision.
Dogs' eyes only have 2 types of cones (just 20 percent of the cones in human eyes). Because of this, a dog's color spectrum is limited to shades of gray, brown, yellow and blue. This is called dichromatic vision, which is similar to humans who experience red-green color blindness.
Having yellow-blue dichromatic vision means that dogs are most similar to a red-green color blind person. They are very good at distinguishing between variations of blues and yellows (and whites and grays), but cannot really see red and green all that well.
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 absolutely can see TV, and many seem to enjoy it. There are a number of features about television shows that dogs find attractive.

Blue and violet are also more emotionally calming and can help to reduce stress levels. These colors are preferable in the veterinary setting because they appear in lighter tones to animals and do not seem as abrasive as white or as dull as gray.
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.
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 cannot see the difference between orange, yellow, or green. However, they can see the color blue, but shades of violet or light purple appear blue to them. This difference means that they are only partially colorblind.
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.

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.
