The Enigmatic Allure of Green Eyes: Unveiling the Rarest Natural Eye Color

TL;DR;

Green eyes are the rarest natural eye color, found in only about 2% of the world's population. This unique shade is the result of a moderate amount of melanin in the iris, which scatters light and depends on multiple genes for pigment distribution. Genetic research suggests that all humans initially had brown eyes until a mutation led to the development of lighter eye colors, including blue and green.
