What is the rarest eye color?
Green takes the crown for rarest eye color in the world, but gray sometimes steals the title in systems that count it apart from blue.
It also depends on what you’re measuring. Are we talking about national vs. international rarity, and do you count rare looks tied to conditions such as albinism? Below, we explore why the answer varies, what causes each rare color, when a color change needs attention, and how colored contacts can switch up your look, with no fancy genetics required.
Which eye color is the rarest depends on how eye colors are classified
Green tops most global lists of the rarest eye color. Only about 2% of people worldwide have green eyes. Gray pulls ahead in counts that treat it as its own color instead of blue’s moody emo cousin. Geography plays a part, too. Green is more common in the U.S. than worldwide, so an American survey and a global one can name two different winners.
Then there are red, pink, or violet-looking eyes (we see you, Elizabeth Taylor), which get a single category of their own. They can be linked to albinism or the way light bounces inside the eye.
What is the rarest natural eye color?
Green, with fine print. Natural rules out cosmetic contact lenses (sorry, violet-lens enthusiasts, those don’t count). And red or pink looks tied to albinism tend to get counted differently from standard rankings.
What is the second rarest eye color?
The second rarest eye color depends on the list you’re reading (sensing a theme yet?). Gray, amber, green, and the occasional write-in candidate are all runners-up in rare-eye-color chat, and the order shuffles based on an array of factors. Many lists slot gray into second place, but it could be green if you count eye colors associated with albinism. It could even be hazel if you think gray hasn’t earned its place on the podium as separate from blue.
How eye color works
Eye color is mostly shaped by melanin in the iris, the iris’s structure, genetics, and how light scatters inside the eye. You may not know that the iris really only has one pigment, and it’s brown. More melanin makes darker eyes, whereas less melanin lets light scatter through the iris, creating the blues, grays, and greens.
As for heredity, your high school biology class probably promised one tidy dominant-or-recessive gene, but real life is messier. A bunch of genes chip in, which is why irises come in seemingly endless shades. Even two brown-eyed parents can have a lighter-eyed kid.
Lighter eyes also let in a bit more light, which is good to know if you deal with light sensitivity and your eyes. The trade-off for blue-eyed folks' better night vision is feeling like the sun’s almighty rays could turn you into dust (pack sunglasses every summer vacation to avoid that vampire feeling).
Rare eye colors, explained
Let’s get stuck into what gives these rare eye colors their mysterious charm.
What makes green eyes green?
Green eyes are linked to low-to-moderate melanin and the way light plays off the iris. Plot twist: there’s zero green pigment in there. The color comes from a small amount of golden-brown (texture like sun?) melanin layered with scattered light, which is why green eyes can look so vivid. That very specific recipe is also why green is uncommon around the globe.
What makes gray eyes look gray?
Gray eyes are thought to come from low melanin plus light scattering, and traditionally got lumped in the blue-eyes category. Gray irises are also thought to have more collagen in the front layer of the iris, which scatters light so the iris has the appearance of a fine mist or stormy skies.
What makes amber eyes look golden?
Amber eyes have a golden, coppery, honey-like, or straight-up-lion tone that sets them apart from brown eyes. Amber is also one solid color from edge to edge (hazel is more of a mixtape). Amber eyes are uncommon enough to appear on plenty of rare-eye-color lists, though where they rank depends, once again, on who’s doing the counting.
What makes hazel eyes look mixed?
Hazel eyes mix brown, green, and golden tones, which makes them harder to sort than single-color eyes. Just keep in mind that one person’s hazel is another person’s green (remember the viral blue dress?). Some hazel eyes even seem to shift shades with an outfit change.
Why do some eyes look red, pink, or violet?
Red, pink, or violet-looking eyes may be linked to albinism or how light reflects inside the eye. When the iris has very little melanin, light can bounce off blood vessels inside the eye and create a reddish or violet look. These fall outside the standard eye-color categories, and they can come with light sensitivity or other vision needs that deserve professional care.
Can your eye color change?
Eye color can seem to change a little with lighting, clothing, age, pupil size, or a flattering camera filter. Sudden or clear changes are a different story. Contact an eye care professional if your eye color changes fast or comes with eye pain, vision changes, injury, signs of infection, allergic reactions, or symptoms that get worse. Curious how much shifting counts as normal? Here’s the scoop on whether your eyes can change color naturally.
Can colored contacts change the look of your eye color?
Yes, colored contacts can change how your eye color looks, from a subtle boost to a full-on switch-up (mystic green, anyone?). Just remember they’re still medical devices that need to be fitted properly, and you need a valid contact lens prescription for purely cosmetic colored contact lenses.
If your prescription has run out, you may be able to renew your contacts prescription online without leaving your couch.
The bottom line on rare eye colors
Considering how many genes influence eye color, there’s an argument to be made that all eye colors are rare. Your eye color is uniquely yours, and something to be proud of, whether it’s brown, green, blue, gray, pink, violet, or red.
If your eye color changes suddenly or comes with symptoms, be sure to see an eye care professional. And if you’d like to borrow a rarer shade for a while, prescription-colored contacts can make it happen safely.
