Combined with the blue hue from the Rayleigh scattering and the yellowish tint from the lipochrome pigment, a green colored iris is produced. Like we said before, only about 2% of the world’s population, or about 140 million people, have green eyes.

WebThe more pigment you have, the darker your eyes will be. Blue, grey, and green eyes are lighter because they have less melanin in the iris. Most people in the world will end up with brown eyes. The next most common colors are blue and grey, and green is the rarest color. Besides giving our eyes color, melanin helps protect them from the sun.
