Improved sight in the dark? :)
Actually I'm not really kidding since men mostly have some 'color-blindness'. So you may have something there. After all the men needed a better night vision since they were the hunters/providers.(ref 1)
Actually what do you mean by color-blindness (check reference 2)?

There is no "evolutionary benefit" to color-blindness to humans at this particular time, which is why, over generations, this trait has not become ever-more prevalent.
"The Island of the Colorblind" is a terrific textbook by Dr.Sachs you might enjoy.

With fewer cones (color receptors) on the retina, there is more room for rods (colorless light receptors). This increases the eye's resolution and enhances night vision, both good traits for hunters to have.

I've heard it has benefits in the army. Colorblind people, apparently, have the ability to see through camouflage.

not really. there's no such thing as evolution, so there are no benefits. there could be God-centered, Creationist benefits, though...
many times blind people have better senses of touch, smell, hearing, and so on than other people...

Yes, people were not as racist since they couldn't determine the color of other people's skin.

no benefit. it doesn't cause you to die, so it stays in the gene pool.
