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 see red and 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 don't differentiate 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
Here is a great site, that shows how they see color and tells how they know> http://www.uwsp.edu/psych/dog/LA/DrP4.htm

I didn't know that we did know dogs are color blind. They can see color, its all just a little blurry.

They see color, just not like we do. Has to do with the cones in the eyes.

OK this is a real general answer. Humans have rods & cones in their eyes. One allows sight in black & white the other allows sight in color. I can't remember which has which function. Dogs only have one (rods or cones) in their eyes. It is the one which allows sight in black & white.

I thought they just couldn't see red. By extensive testing, I assume.
