Dogs suffer from a type of colorblindness that in humans is called deuteranopia. Normal humans have three types of color receptors for red, green, and blue. Deuteranopes lack the green receptor, and thus (apparently) can't tell a lemon from a lime--or, for that matter, a red traffic light from a green one.
They also have a higher ratio of rods (light-dark sensitivity) to cones (color sensitivity) than humans, thus better overall vision, but they're hell when it comes to interior decorating.

Dogs are red-green color blind. They see a brighter and less detailed world when compared to humans. Peripheral vision is better than humans (dogs see more of the world), but distance is not judged quite as well. Dogs excel at night vision and the detection of moving objects. Figure 1 is a rough guesstimate of what a dog and human might see when viewing a color band (the electromagnetic spectrum).

Scientists believe that canines can see part of the range of colors in the visible spectrum. Humans like you can see all the colors--red, orange, yellow, green, blue, indigo, violet--but dogs probably see mostly in shades of yellow and blue. But remember, this is only a THEORY, since we can't really find out if a color appears the same way to dogs as it does to people.

Dogs see in color, but their perception of color is not the same as it is for people. They cannot distinguish between red, orange, yellow or green. They can see various shades of blue and can differentiate between closely related shades of gray that are not distinguishable to people.
When comparing dog and human vision, people are better at depth perception, color perception and seeing minute details of an object. Dogs are better at seeing in dim light, responding to an image rapidly and detecting the slightest motion. They also have better peripheral vision.

Popular wisdom has it that dogs are color-blind, but recent research suggests that a dog's world is not all black and white.

Dunno, when my dad was a kid he had some kind of terrier that whenever a GREEN truck drove by (and they lived on farm if it makes a difference) the dog would bark and run to the road. No other color, just green.
However, my parents had some kind of mutt when they got married and she only barked when she saw black & white spotted cows. No other colors made her bark.

My understanding is that they see like color-blind people see. It's not black & white. They see a small spectrum of colors (like reds and greens or something like that).

Yes they see things in black & white. They depends loads on sense of smell!

it's not black and white. it's a greenish color. and no dog can see color as someone previously said. they can tell by the contrast between colors that make the green color they see a light green / dark green and differintiate between objects and people that way.

I am certain that one of my dogs can tell teh difference between colors. I have a garden flag and change it frequently. She can always tell when I've changed it, because she stops and stares at it.
