Since babies dont receive a lot of light exposure, they tend to have fairer skin, hair, and eyes than adults. The longer your eyes were exposed to light, the more melanin pigments your irises produced.
Since natural sunlight is often brighter than artificial lights, exposure to it might allow you to see colors in your irises that you couldnt recognize before. If youve developed a rare condition called heterochromia, your eyes likely have changed color significantly. Central heterochromia refers to a condition where your iris has two different colored rings.

It is particularly dangerous for eyes to change from brown to green, or from blue to brown. Major changes in the iris’ pigment can indicate illness, such as: Horner’s syndrome.
What is the rarest eye Colour?
The production of melanin in the iris is what influences eye color. More melanin produces a darker coloring, while less makes for lighter eyes. Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer. Eye color isn’t just a superfluous part of your appearance.
Eye colors depend on how much pigment resides in the iris the eye structure that surround the pupil and often is called the colored part of the eye. There is only one pigment that determines eye color: It’s called melanin.
The influences from each parent on eye color aren’t fully known until after the child is born and begins to mature. In the United States, about 40% of the American population has brown eyes (all shades included).
Some surveys suggest green eyes also are considered the most attractive eyen color. It appears this is caused by more melanin developing in the iris during infancy and early childhood. Most individuals achieve stable eye color by 6 years of age .
However, a subpopulation of 10% to 15% of Caucasians can have changes in eye color throughout adolescence and into adulthood. But some people can have a pigment “freckle” (called a nevus ) on one part of their iris. It’s also possible to have a variation called heterochromia , where a small or large section of your iris has a different color than the rest of your eye.
The colored part of your eyes is called the iris. While some people have blue eyes, others have green or brown. Some are more blue-green or hazel. Everyones eye color is a bit different. Heres what you need to know.

How Does Eye Color Develop?
When you were born, you likely had blue eyes. Babies’ eyes display this color because their bodies and eyes contain low levels of melanin. Melanin is a pigment that gives your eyes, skin, and hair their color. Once your body became exposed to light, it started to produce melanin, which in turn changed the color of your hair, skin, and eyes.Since babies don’t receive a lot of light exposure, they tend to have fairer skin, hair, and eyes than adults. However, genetics also factor into skin, eye, and hair color. For example, if your parents have darker skin and hair, then you likely had those same dark pigments in your skin and hair when you were born.Your eye color, however, probably took a little more time to develop. The longer your eyes were exposed to light, the more melanin pigments your irises produced. But depending on your genetics, your eyes could have turned dark brown. Or maybe your eyes didn’t darken much and they stayed light blue. So regardless of how much or little light exposure you have, your genes determine how light or dark your eye color is.
When Can Eyes Change Color?
Typically, a person’s eye color becomes permanent about three years after birth. Once eye color has set, the color usually won’t change. However, several factors can influence your eye color and whether or not it changes to a different pigment.
Increased Sun Exposure
As previously mentioned, exposure to light causes your body to produce more melanin. Even if your eye color has set, your eye color could slightly change if you expose your eyes to more sunlight. As a result, your eyes might appear a darker shade of brown, blue, green, or gray, depending on your current eye color.Sunlight can also reveal colors that were already in your eyes. Since natural sunlight is often brighter than artificial lights, exposure to it might allow you to see colors in your irises that you couldn’t recognize before.
Changes in Pupil Size
Your pupils’ size can also cause your eyes to change color. When your pupils shrink or dilate, the color of your eyes may seem to change. For example, if your pupils widen, not as much of your irises are exposed, and the remaining irises look darker.On the other hand, when your pupils are smaller, your eye color may appear lighter. This change is due to the contrast between the black of the pupil and the surrounding iris.
Clothing You Wear
If you think back to your elementary, middle school, high school, or even college art classes, you’ll remember that complementary colors enhance one another. When reds and greens are placed together, the reds appear more vibrant while the greens appear more lush.This principle applies to eye color as well. If you wear certain colors of clothing, the pigments in your shirt, jacket, tie, or scarf could temporarily change the color of your eyes. Depending on the color you wear, your eyes may appear lighter or darker.
What causes different eye colors?

Are eye colors genetic?
Yes and no. A child’s eye color definitely isAt one time, brown eye color was considered “dominant” and blue eye color was considered a “recessive” trait. But modern science has shown that eye color is not that simple.Eye color isn’t just a blend of the parents’ eye colors, as in mixing paint. Each parent has two pairs of genes on each chromosome, and multiple possibilities exist for how this genetic information is expressed in terms of eye color. The influences from each parent on eye color aren’t fully known until after the child is born and begins to mature. [Read more about eye color genetics.]

How Eye Color Is Determined
In the past, people believed you could predict the eye color of children by looking at the eye colors of the parents and grandparents. Based on the belief that brown eyes are a dominant trait and blue is recessive, you could get a good idea of what color the child’s eyes would be.Today, we know that eye color isn’t as easy to guess as looking at the parents’ eyes. While genetics does play a role, eye color is not the work of a single gene. Instead, several genes contribute to determining eye color.Your eye color is the result of the amount and distribution of melanin (a natural pigment) in your irises. Brown eyes have more melanin in them than blue, and there are various shades in between. Darker eyes tend to be more dominant, but as different genes factor in, this doesn’t mean darker colors always win out.So, while two brown-eyed parents are more likely to have a child with brown eyes, the result isn’t a guarantee. Nor will it always be the case that a child of one brown-eyed and one blue-eyed parent will have brown eyes.Approximately half of all people in the U.S. have brown eyes. The color is also more prevalent in areas of the world with warmer climates. People with blue eyes have no melanin in the stroma, the front layer of the iris. The lack of pigment in the eyes causes light to scatter when it hits them, making the irises appear blue.Green eyes are the rarest. Only about 2% of the world’s population has green eyes. The color comes from both melanin and the effect of light scattering when it hits the eye.People born with albinism often have little to no melanin in their bodies. As such, they typically have light blue eyes. In rare cases, they may have clear irises, which can make their eyes look pink or red.
Can Eye Color Change?
