Blue-eyed black lemur. Winner of best eyes is the blue-eyed black lemur. It's a tiny bit of a misnomer because only the males are black; the females are a reddish-brown color. Both colors help their striking blue eyes stand out.

Brown eyes have a lot of melanin in the iris, green eyes have less, and blue eyes have little or no pigment. Two genes, bey2 and gey, work together to make brown, green, or blue eyes. Each gene has two versions or alleles.
