From Wikipedia: "Individuals with Northern European ancestry, as many as 8 percent of men and 0.4 percent of women experience congenital color deficiency"
I have read there is a survival of the fittest factor to it. In Northern European forests seeing all colors can be an overload that animals like deer take advantage of with there camouflage.
