Green eyes come from a combination of both types of melanin in low enough levels to also get a bit of the light scattering effect. The pigment itself isn’t blue, but the way the light scatters around the front layer of the iris ends up appearing blue - the same way the sky appears blue! Blue eyes, on the other hand, get their color from having relatively little eumelanin. There are two different types of melanin a person could have in their irises: eumelanin, which produces a rich chocolate brown color, and pheomelanin, which produces a range of amber, green, or hazel colors. Melanin absorbs light, even some UV light, which is important for the iris - the part of the eye that controls how much light enters the pupil. Human eye color comes from melanin, the same compound that determines skin and hair color.
