As melanin decreases, the eyes appear greener, greyer, or finally blue, as the collagen in the stroma scatters light through a phenomenon known as Rayleigh scattering. Understanding the Spectrum of Iris Color To identify the rarest eye color, one must first understand the gradient that exists between common and uncommon.

The question of what is the rarest eye color in the human population often leads to a simple answer, but the reality is a fascinating journey through genetics and biology. Hazel eyes, which often display a mix of green and brown with flecks of gold, are significantly less common but still relatively widespread.
The distinct green hue is a result of moderate melanin levels combined with the yellow pigment lipochrome and the blue scattering effect. People of Irish, Scottish, or Northern European descent are most likely to possess this trait.

High melanin concentration results in brown eyes, which are the most dominant globally. This occurs due to variations in the concentration of melanin in each iris or a segmental difference affecting only a part of one eye.
