Well, you might want to call Hollywood to complain, because filmmakers have been getting it all wrong. Dogs do not see in black and white, but they are what we would call "color-blind," meaning they have only two color receptors (called cones) in their eyes, whereas most humans have three.

What color do dogs see?

Dogs possess only two types of cones and can only discern blue and yellow - this limited color perception is called dichromatic vision.

What colors do dogs don't see?

Dogs can only see blue, yellow and some shades of gray. Dogs would see a rainbow as dark yellow (sort of brownish), light yellow, gray, light blue and dark blue. Dogs don't see red, purple (violet), or orange as we do.
