I've read here several times that brown eyes lighten more quickly than green or blue eyes, but I don't understand how would that make sense.
The science says there is no blue or green pigment, the color of the eyes would be blue if there is no or very little melanin and the blue color comes from the reflexion of the light-similar effect as the blue color of the sky. With little more melanin you get green color, with some more light brown,even more dark brown and black.

So in green eyes is the concentration of melanin smaller, so my logic would be that it lightens faster, because there is simply less melanin to get "rid off"

doesn't that make more sense?
