Here is a site that your brother will love to see, as it shows just how a dog sees colors> http://www.uwsp.edu/psych/dog/LA/DrP4.htm
dogs do see many colors, but can't tell red from green...so, by human standards, they are color-blind..but they do see much more than black and white..they see blues and yellows, tan/browns, and some purlpes..
BOTH answers are correct, depending on context.
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 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

Dogs are colourblind but some are now debatting whether or not it is true that they only see in black and white. Some mean that it is closer to the colours of brown but I personally stick with black and white. There is also no doubt that although their vision might be impaired, their sense of smell is highly sophisticated.

dogs = b/w. absolutely no color at all.
they also have a poor sense of taste so no point feeding them good tasting food.
update
In Human Biology terms:
not seeing red and green= partial colour blindness
seeing b/w only = total colour blindness
since dogs are so smart why not trained them to differentiate between colors . " come on Rex, fetch the purple ball. No Rex no! not the orange ball!!!

From what the web site says, they see red green, it isn't really black and white, but they are basically color blind.

Dogs do not have color rod receptors in their eyes. they only see in black and white.

Black and white is how they see everything. No pun intended.
