Heterochromia — <1% of the Population Heterochromia is the rarest natural eye color trait in the world. Less than 1% of people have it — when one eye (or part of one eye) appears a different color from the other. This happens due to variations in melanin levels between or within the irises. Ginger Brown + Honeymoon Ocean There are three types of heterochromia: Complete Heterochromia: Each eye is a totally different color (e.g. one green, one brown). Sectoral Heterochromia: A portion of one iris is a different color. Central Heterochromia: Both eyes have a ring of another color around the pupil. It can be genetic and appear at birth, or develop later due to trauma, inflammation, glaucoma, or conditions like Horner Syndrome and Sturge-Weber Syndrome. Despite how it looks, it’s usually harmless and simply adds a unique charm. 2. Violet Eyes — <1% of the Population Violet eyes are extremely rare and are typically seen in people with albinism. These eyes don’t contain violet pigment — instead, a lack of melanin allows light to reflect in a way that creates a purple-toned appearance, especially in certain lighting. In some cases, violet eyes may appear blue, grey, or even red-tinged depending on lighting and surroundings. The rarity and mystery around violet eyes have made them iconic in pop culture and fantasy. Celebrity connection: Actress Elizabeth Taylor was famous for having eyes that appeared violet under studio lights, although they were technically deep blue with strong red and blue light reflection. Violet-colored contacts are a beautiful way to achieve this ethereal, otherworldly look — especially when paired with cool-toned makeup or icy lavender tones. Iris Lavender + Waterfall Blue 3. Green Eyes — 2% of the Population Green eyes are among the most captivating and rare — found in only 2% of the global population. They’re caused by a low level of melanin combined with the Rayleigh scattering of light, which gives the iris a soft green or golden tone. Unlike hazel, green eyes are usually a single, consistent shade. They're most common in people of Celtic and Northern European ancestry, but they appear in other populations too. Symbolism & beauty: Green eyes have long been associated with mystery, enchantment, and vitality. They’re often the focus of poems and fantasy characters for their intense, hypnotic look. Romantic Green + Green Olive 4. Grey Eyes — 3% of the Population Grey eyes are both subtle and mesmerizing, appearing silvery, icy blue, or even smoky depending on the lighting. Around 3% of the population has true grey eyes, which have even less melanin than blue eyes and more collagen in the iris. They’re most common in Eastern Europe and Northern regions, and are often mistaken for blue. What makes them unique is their ability to shift color — appearing silver in daylight and slate-toned at night. Fun fact: Grey eyes are considered a neutral base, making them perfect for bold makeup looks or cool-toned lenses that enhance dimension. Passion Pearl + Exotic Grey 5. Amber Eyes — 5% of the Population Amber eyes are known for their golden, copper, or honey-colored glow. Unlike hazel eyes, which have flecks of multiple colors, amber eyes are typically a solid, rich tone caused by higher levels of lipochrome (a yellow pigment). They’re rare and most commonly found in South America and parts of Asia. Amber eyes give off a warm, feline energy that instantly stands out in both daylight and photos. Style tip: Amber-toned contacts look especially radiant against olive and warm skin tones. Desire Honey + Pacific Grey 6. Hazel Eyes — 5% of the Population Hazel eyes are a beautiful mix of green, brown, and gold — shifting in color depending on lighting and what you’re wearing. Around 5% of the population has hazel eyes, and they often contain multicolored flecks or radiating streaks. This color is often confused with amber, but hazel has more variation and depth. It's also one of the most adaptable eye colors when it comes to styling. Learn more: Why Hazel Eyes Are Rare & Beautiful → Brown Bear + Green Olive 7. Blue Eyes — 8–10% of the Population Blue eyes are often romanticized — but they’re still relatively rare, found in only about 8–10% of the world. They result from a lack of melanin and rely on light scattering to produce that icy, clear appearance. From icy steel to bright baby blues, they vary by lighting, genetics, and even mood. Blue eyes are more common in people of European ancestry and tend to appear lighter in younger people. Want more inspo?
