Are dark olive green eyes rare?

Dark olive green eyes are one of the rarest eye colors in the world. They are a unique shade that appears to shift between green, brown, and gray. But just how uncommon are these mesmerizing peepers? Let’s take a look at the data and find out.

What Causes Dark Olive Green Eye Color?

Eye color is determined by the amount and quality of melanin pigments in the iris of the eye. Melanin comes in two forms:

  • Eumelanin – Brown and black pigments
  • Pheomelanin – Red and yellow pigments

Most people have a combination of both melanins in their iris, resulting in eye colors like brown, amber, or hazel. Green eyes are rare because they have very low levels of melanin overall. Instead, they contain a yellowish pigment called lipochrome.

Dark olive green eyes get their complex coloring from having both lipochrome and small amounts of melanin. The melanin adds flecks and streaks of brown, gray, and olive to the golden-green base. This mixture creates a multicolored swirl that almost appears to change shades in different lighting.

Global Prevalence of Dark Olive Green Eyes

Worldwide, only about 2% of the population has green eyes. This already small percentage includes all shades of green, from light mint to deep emerald. Within that 2%, dark olive green eyes make up just a tiny fraction.

Here is a breakdown of green eye prevalence by country:

Country Percentage of Population with Green Eyes
Iceland 88%
Ireland 86%
Scotland 57%
England 48%
Germany 10%
Spain 9%
Italy 7%
Greece 5%
Netherlands 4%
Austria 3%

As you can see, green eyes are most common in northern and western European countries. This is due to genetic factors tracing back to Norse, Celtic, and Germanic ethnic groups. But even in those populations, true dark olive green eyes are rare.

Genetics Behind Dark Olive Green

For a person to have dark olive green eyes, they must inherit genes for low melanin from both parents. Mother Nature really has to come together to create this eye shade!

Here are the main genetic combinations that can result in dark olive green eyes:

  • Parents both have blue eyes – Resulting child will have very little melanin overall, allowing olive undertones to show through
  • One parent has blue eyes, one has green or hazel – Reduced melanin from the blue-eyed parent dilutes melanin from green/hazel parent
  • Both parents have green or hazel eyes – Very rare; child inherits ideal melanin levels to create dark olive hue
  • One parent has green eyes, one has brown – Low melanin from green-eyed parent limits brown melanin from other parent

As you can see, the genetics have to be just right. A delicate balance of eumelanin and pheomelanin levels is needed to produce those enchanting flecks of olive, gray, and brown.
