Ever watch a black and white TV? There are still shades of gray. It's still possible to distinguish between skin colors.

Yea because when I watch something in black and white I can't tell who the black people are at all!!

Dogs don't actually see in black and white, they see in shades of blue-ish and yellow colours.

Where is everyone getting the idea that dogs see in black and white?

meow234: I don't know. People should do their research before they start stating things like they're facts. Which is why I did: According to Pedigree.com "Veterinarians used to believe that dogs saw only in black and white, but recent studies suggest that they actually do have some color vision—but it's not as bright as a human's. As it turns out, dogs have only 20% of the cone photoreceptor cells—the part of the eye that controls the perception of color—that humans have." So they have SOME color vision, just not as much as we do. kidpurp: I hope you realize you contradicted yourself. "dogs can only see in black and white." "black people." Made the connection yet? You should think about changing your name to kidderp.

Are you kidding me?
