Brown Eyes
The world’s most common eye color — and one of its most varied.
Classic · 70–80% of people worldwide
Blue Eyes
Not blue pigment at all — structural light scattering.
Uncommon · 8–10% of people worldwide
Green Eyes
The rarest of the common eye colors.
Rare · ~2% of people worldwide
Hazel Eyes
Two colors in one iris — and never the same twice.
Rare · ~5% of people worldwide
Amber Eyes
A solid golden-copper iris — often called wolf eyes.
Rare · Under 5% worldwide, and much rarer in some regions
Gray Eyes
One of the rarest eye colors — blue’s mysterious cousin.
Very rare · Under 1% worldwide
Central Heterochromia
A ring of a different color around your pupil.
Rare · No reliable global statistics — uncommon, often unnoticed
Heterochromia
Two different eye colors on one person.
Exceptionally rare · Complete heterochromia: very rare (well under 1%)
How eye color works
Every eye color is the same two ingredients in different doses: melanin (brown-black pigment) and the iris structure that scatters light. Lots of melanin reads as brown. Almost none reads as blue or gray — those aren't pigments at all, but light scattering off nearly-empty tissue. The in-between amounts, sometimes with a golden pigment called lipochrome, produce green, hazel, and amber.
That recipe also sets the rarity ladder. Brown is the global majority. Blue covers roughly 8–10% of people, hazel about 5%, amber about 3%, green about 2%, and gray around 1% — with patterns like central heterochromia rarer still. Where you live changes the experience: green is unremarkable in Dublin and remarkable almost everywhere else.
One thing the labels hide: almost nobody is a single color. Real irises are mixtures — brown with gold flecks, green with a gray rim — and the label you were assigned as a child is often just your dominant family. That's why each page below ends with the same offer: measure the actual mixture, in your browser, from one photo.
