Dogs can see certain colors, but not the same as people. They can't establish between red, yellow, orange and green.
They see blue and they also see a larger number of shade of gray compared to people.
They can also distinguish certain colors better in the dark.

A dog"s sight is the most import of its senses. It's not as developed as in humans, since the dog can barely differentiate different colors (which it confuses in a gamma of sepia hues), or their depth, although their field of vision is much broader than ours and has great reflex toward movement; which is where its skill is when sighting its prey when hunting. The dog's field of vision is very wide: from 200 to 270 degrees (depending on the size of its snout and the skull's shape) compared to man's 160 degrees. Their eyes are very similar to a human's, but the ocular globes have less movement. A
human's sight is binocular and forward, while a dog's are laterally. Humans have much better sight than dogs, especially when it comes to small objects, yet dogs, because of the location of their eyes can detect a movement behind them. Dogs are farsighted and detect moving objects much more than immobile ones. On the other hand, they have excellent night vision since they have a special membrane that allows them to receive light.
So yes a dog can see colors they just can't differentiate them.

Actually dogs can see some shades of color, just not as well as humans can. Through research they found the black and white theory was false. The dogs eyes have evolved to detect motion much better than humans - to help with hunting. They are also much better than humans at seeing in low light situations - again for hunting and survival at night. Color vision is not important to dogs for survival in the wild so their ability to detect it is less than ours.

This is a toughie.
Dogs do not only see in "Black and White" as most people think, but they do not see things with as much detail as the human eye.
They can see some darker shades, like red.
Though true, they do not see as many colors as the human eye, they do not only see black and white.

Popular wisdom has it that dogs are color-blind, but recent research suggests that a dog's world is not all black and white. To understand what dogs can and can't see, it helps to have some basic knowledge of vision in humans and other mammals.
We began by searching on "dog vision color," which took us to a page from the National Hunting Retriever Association site. Summarizing a 1995 article originally published in the Journal of the Veterinary Medical Association, the page describes the fundamental design differences between canine and human vision. Our vision is optimized for seeing in bright light, while dogs, like many other predators, see best in dimmer light.
How Vision Works describes the anatomy of seeing and the role of the retina, a structure at the innermost layer of the eye that senses light and sends visual information to the brain. Two types of photoreceptor cells in the retina -- rods and cones -- respond to light and transmit electric impulses to the optic nerve through a series of chemical reactions. Rods process visual information in dim light and are sensitive motion detectors, while cones handle color and detail. The human retina contains approximately 100 million rods and 7 million cones.
dogs can see a few colors but their night vision is much better than ours.
Cone cells contain pigments that perceive specific wavelengths of color. Human vision is trichromatic -- we have three types of cones that recognize different portions of the color spectrum. These cones allow us to see a range of colors that are a mix of red, blue, and green pigments. Dogs have only two types of cones -- their dichromatic color vision is similar to that of a human with red-green color-blindness. In addition, a dog's retina contains a much smaller ratio of cones to rods than ours does. An article about Canine Vision, written for a college psychology course, includes a graphic that contrasts the yellow, blue, and gray spectrum of the dog's world with the familiar rainbow of colors we perceive.
Before you start feeling sorry for Fido, keep in mind that although he may not have the color range and visual acuity (focus) that you depend on, his night vision is far superior. Thanks to a reflective structure behind their retina called the tapetum lucidum, dogs see objects in the dark as if lit by an eerie glow.
If you want to learn more about the mechanics and evolution of color vision, an illustrated account titled Color Vision: Almost Reason Enough for Having Eyes will increase your understanding.

According to scientists, no. They see in shades of grey, like watching a color t.v. show in black & white. Different shades of grey represent different colors.
