Why are blue eyes not naturally blue?

What is the blue pigment for eyes?
There is no actual “blue” pigment for eyes. People with brown eyes have them because melanin is a brown pigment. Blue eyes simply appear blue because the lack of melanin causes light to split into a color spectrum. This effect is known as Rayleigh scattering. The result of this scattering of light is blue light hitting the top of the iris.
Why are some people blue-eyed?
