Rarest Eye Color: Facts and Figures

The rarest eye color ⁣in the world is a captivating‍ phenomenon. Despite being⁤ a subject of fascination and debate, facts and figures about this mysterious eye color remain elusive.⁢ This article seeks to explore the rarest eye color, unearthing facts and figures ‍that underpin the discussion.

Introduction to ⁤Rarest​ Eye Color

Rarest​ Eye Color

Rarest eye color is a rare ⁣form of eye pigmentation characterized by unusual hues and shades. Generally ‌only seen in around 6-8 percent of the population, rare eye colors can range from ⁣solid blues and greens to vibrant golden ochres and ​smoky browns.

Types⁢ of Rarest Eye Colors

  • Ice Blue Eyes- Commonly seen in 5-8 percent of the⁣ population,⁣ these unique shades ‍of light ‌blue have a frosty, almost iridescent sheen.
  • Amber Eyes-​ Either a ⁣bright orange or ‍a⁣ yellow-gold, amber eyes are known for their brightness.
  • Violet Eyes- A very rare eye color, violet indicates an abnormal concentration of yellow pigment‍ in the​ irises.

Rarest eye colors determine the amount and type of melanin produced in the eyes, as they don’t typically occur from a single‌ gene mutation‌ or a pair ‌of alleles. Instead, they are caused by⁤ a rare combination of melanin deposits in the eyes.

Eye color ⁣is ⁤a⁣ complex form of genetic inheritance in humans, and the color‍ of the rarest eye varies greatly from one person​ to another.

It is also possible for rarer shades​ of eye colors to change‍ as a person ages. Melanin deposits in the eyes gradually increase with age, and depending on the⁢ amount of pigment in the person’s iris, ‌the shade ​may lighten ⁤or darken as the person ‌matures.

Rarest eye colors tend to be more vibrant and ‍unusual than other forms⁣ of eye pigmentation, given their rarity and their unique range of shades and hues.

Knowing the ⁤different types ⁤of ⁢rare eye colors can help to identify whether a person has a rare eye color, and thus give ‌them a more accurate view of their  ⁢genetics.

Types‌ of Rare Eye Colors

Yellow Eyes

As one of the rarest eye colors, yellow is ⁣sometimes seen ​in ‌the eyes of people⁣ of Asian‌ descent.‍ It has a light yellow hue and appears in shades‍ ranging from golden to light yellowish-brown. It can have flecks of orange, green, or ⁣brown.


Heterochromia is a condition ‍in which two eyes have different colors. Most often one eye is completely brown and the other is blue or partly blue, but other combinations of color ⁤can⁤ also occur. Heterochromia is very rare ‍and is almost always⁣ present at‌ birth.

Other‌ Rare Eye Colors

  • Gray
  • Violet
  • Red

Gray eyes are the rarest, although many people have a blue/gray combination. Violet eyes are⁤ a ⁣deep, saturated shade of blue between blue and purple. Red eyes ⁣also exist, although they are very rare and may be confused with super-dark brown eyes in some cases. These rare eye colors are difficult to genetically explain.

Causes of Rare Eye Colors

Rare⁤ eye colors, ​such ​as green and hazel,​ are‌ caused ⁢by⁤ a combination of genetics,‌ melanin, and other ‍factors.


Eye color is determined by several traits that are passed from both parents to their⁢ children. Genes for rarer eye colors such as⁤ green or hazel are much rarer in​ the gene pool, which is why those colors ​are considered rare. As⁣ such, these colors⁣ are only seen when both parents⁤ possess ⁣these⁢ gene ⁢variants and pass​ them on to their children.


Melanin is a pigment found in the eyes that⁣ influences eye color.⁤ The amount of melanin in ⁤a person’s ‌eyes determines their ⁢eye color, with⁢ higher melanin levels producing darker eye‌ colors. In cases⁢ with⁣ rare eye colors such as ​green or ​hazel, people have lowered amounts of melanin, giving their eyes a lighter hue that we⁤ consider​ rare.

Other Factors

  • Sun‌ Exposure – Prolonged exposure to UV⁣ rays from sunlight can trigger⁢ changes in melanin levels that may⁤ affect eye color.
  • Age – As we⁤ age,⁤ the melanin levels in our eyes may​ change, resulting ⁢in a different eye color.
  • Mutations – Rare genetic mutations can cause changes in eye color, such as‌ the mutation ​that causes heterochromia.

Rare eye⁢ colors have a variety of causes, from⁢ genetics to age and mutation, but⁣ they are all linked to the levels of melanin in the eye. Without the⁢ combination⁣ of these factors, rare eye colors could not exist.

Distribution of ‍Rare Eye Colors

The rarest eye colors are ‍those most⁢ likely ​to draw attention. ⁣Even ⁢though they make up less than 2% ⁢of the ‍population, they are ‌still quite common. Here is an overview of the distribution of ⁤rare⁢ eye colors.

  • Gray – Gray eyes are rare, with less than two ​percent of people having them worldwide. They​ are found mostly in Europe ​and ⁢parts of ⁣Russia and⁤ Africa.
  • Hazel – Hazel eyes are also rare, ‌though somewhat less than ⁤gray. ‌They are most often⁤ seen in various parts of Europe and some parts of South Asia.
  • Amber – Amber eyes are especially ⁤rare, with less than ⁣one percent of the world’s population having them. They are most⁣ common in ‌North Africa and Southeast Asia.
  • Violet – Violet eyes are extremely rare, and ⁣most likely to be found in⁤ areas such as Europe,‍ Turkey,⁣ and even Colombia. They are believed to occur in less than 0.01 percent of the world’s population.

Although rare eye colors ​can be found in all parts of‍ the world, there is no significant correlation ​between a⁢ person’s geographical⁣ location and the ⁢color of their ​eyes. ⁤Moreover, rare ⁢eye colors are not necessarily ​connected to any particular ethnic group, either.

That ⁤said, certain conditions⁤ such as albinism can contribute to someone having‍ one of these‍ rare⁣ eye colors. Additionally, some rare eye colors are specific to certain races, such as the blue eyes associated with the Pleiades star system.

Health Implications of Rare⁢ Eye ​Colors

Rarest Eye Color: Facts and Figures

Rare eye colors, such as ‍different shades of green,⁤ are surprisingly common. Some estimates ‌suggest that about 2-8% of the world’s population has them. Despite their ubiquity, there ‌is‌ still much about them that we do not understand from an‍ ocular and​ medical perspective.

Possible Short-Term‌ Effects

Certain rare eye colors ⁤are associated with photosensitivity and possible light sensitivity, including:

  • Entopic ‍miosis, or constriction of‍ the pupil
  • Meningeal sensitivities
  • Glaucoma

These conditions can cause ⁣ short-term, but often disabling effects,⁢ like temporary vision​ impairment, headaches,‌ and⁢ fatigue.

Risks of ​Long-Term Effects

In spite of this, the cause-and-effect of⁣ rare eye color and long-term health effects is still up for debate. A few studies have suggested possible associations, including a‍ higher ​risk⁢ of developing cataracts or glaucoma.

However, a more definitive answer requires a much‌ larger, ‌population-wide study, given that the effects ‍of a rare ‌eye color likely⁣ differ according to age and genetics.


Q:⁢ What are the rarest eye colors in the⁢ world?

A: ‌The‌ rarest‍ eye colors ​in the world are red and ⁤purple, also known as alexandrite and ‌amethyst.

Q: How ⁢common are red ⁣and purple eyes?

A: Red and purple⁣ eyes are‌ extremely rare, occurring in less than 1% of the world’s population.

Q:​ Are all people with red or purple eyes⁣ born with these eye colors?

A: No,⁤ not all people with ⁣red or purple⁣ eyes are born with these eye colors. In some⁤ cases, an individual’s ⁤eye color can change from blue to red ​or purple over time due to certain ‍medical conditions or medications.

Q: Are red and purple eyes caused ​by genetics?

A: Yes, red⁢ and⁢ purple⁤ eyes are caused by genetics, but mutations are usually required‍ to​ achieve these colors.


Overall,⁤ the rarity of unusual eye colors remains a subject of fascination for ​many. It’s clear that‍ further ​research is needed in order to scientifically prove the ‌causes of these⁣ unique and remarkable⁤ hues. For now,⁤ there appears to be an array of environmental, genetic,‌ and other variables at play in this ⁤fascinating issue.
