they see blues, yellows, and tan/browns quite well, and some purples. Here is a great color chart, and it tells how they know what a dog sees> http://www.uwsp.edu/psych/dog/la/drp4.ht...
When a man is tested in the military, or for a commercial driving license, the chart tests for color blindness. If he is deemed color blind, it means he can't differentiate red from green, but only sees them as shades of brown..that is the human condition known as color blind.
However, dogs do not differentiate between red and green, so by human standards, yes, they ARE color blind.
But, some people think that the term means that color blindness is seeing only in black and white...dogs DO see other than black and white and shades of gray..so, they do see color.
They see yellow, blue, and tans/browns very well, and some shades of purple..but they can't tell red from green.
So, do they see color? YES
Are they color blind by human terms? YES
Do they only see black and white? NO

Yes, dogs can see colour.
Seeing the world through your dog's eyes is not as simple as renting an old black-and-white movie. The canine eye contains a variety of photoreceptors, or light detectors, that allow the animal to see. Some are shaped like rods, some like cones. Cone-shaped photoreceptors are the basis for color vision. Because dogs' eyes have significantly more rods than cones, researchers once believed dogs saw only in black and white. Research conducted in the 1980s at the University of California at Santa Barbara indicated otherwise: The studies revealed dogs could distinguish between a red ball and a blue ball, white light and colored lights, and closely related hues of violet and blue. They cannot make a distinction between colors from greenish yellow through orange and red. As more research is done, our limited understanding of canine vision is sure to shift again.
Veterinary ophthalmologists have determined that dogs are like people with red/green color blindness: They only have receptors for bluish and greenish shades, not for reddish ones. So, when a person with normal vision sees an orange ball on a grassy lawn, a dog sees only a greenish ball in greenish grass.

Dogs can see some color but not like humans or cats, they have a hard time distinguishing green and red.
They use their noses, that is how they can tell what they are eating and like most dogs they aren't too choosy about what they eat.

I guess it depends on the dog. Some dogs just can't see any colors, and some can see a few, although their best sense is their smell.

No, dogs are color-blind. They simply don't have the eye structure to see colors.

Most dogs are color blind. One dog that is not color blind is a poodle. They know what they are eating by smell not sight.
