What is the rarest eye color? Eye color is determined by the amount and type of pigmentation in the eye’s iris. Depending on the amount of melanin present in the iris, different shades of blue, green, brown, grey, and even hazel can occur. The rarest eye color in humans is usually green, with only about 2 percent of the population having it.
Rarest Eye Color: Green
Green eyes are the rarest color. Green eyes are found mostly in European countries. They can also be found in western and central Asia and parts of the Middle East. Some scientists believe that green eyes are more prominent in people of Celtic and Germanic ancestry. People with green eyes have a small amount of melanin in their iris. The greater the amount of melanin, the darker the eye color.
Rarest Eye Color: Amber
Amber eyes are a very rare and unique color. They are usually found in parts of Asia and South America. Amber eyes are a result of low levels of melanin and Rayleigh scattering, which is the scattering of light off of the proteins and lipids in the eye’s iris. The eye color can range from yellow to golden brown.
Rarest Eye Color: Gray
Gray eyes are also a very rare eye color. They are mostly found in Northern and Eastern Europe. Gray eyes are caused by an even lower amount of melanin than green eyes. This results in a lighter eye color that can range from pale gray to charcoal.
Rarest Eye Color: Red/Violet
Red and violet eyes are extremely rare. They are usually the result of albinism, a genetic condition in which the body does not produce enough melanin. This results in a pinkish or reddish eye color. People with albinism may also have vision problems.
Other Rare Eye Colors
Other rare eye colors include:
- Hazel – Hazel eyes are a mix of brown and green, usually with a golden or copper tint.
- Blue-Gray – Blue-gray eyes are a mix of blue and gray, usually with a slight hint of green.
- Silver – Silver eyes are very light gray or blue-gray, often with flecks of gold or brown.
The rarest eye color in humans is usually green, with only about 2 percent of the population having it. Other rare eye colors include amber, gray, and red/violet. Hazel, blue-gray, and silver eyes are also considered rare.
