Brown eyes are one of the most common eye colors in the world. In fact, brown eyes are so common that, according to World Atlas, approximately 55% to 79% of the world’s population has brown eyes. While this dominates the eye color gene pool in many parts of the world, it is often far less common in some regions such as sub-Saharan Africa, where green, blue, and hazel eyes are more prominent.
In the United States, approximately 79% of Caucasians, 89% of African Americans, and 87% of Hispanics have brown eyes.
In terms of other countries, some areas have differing percentages of brown-eyed residents. For example, countries in East and South Asia have some of the highest percentages of brown eyes, with approximately 95% of people in India having brown eyes, 98% in Japan, and between 90 and 95% in China having brown eyes.
Overall, brown eyes are the most prevalent eye color in the world, making up for the majority of the population’s eye colors. While slightly lower percentages are present in some countries, the vast majority of people still have brown eyes.

What is the rarest eye color?
The rarest eye color is thought to be green. Only 2 percent of the world’s population has green eyes. Green eyes have low levels of melanin, and they are often described as blue-green or greenish-blue in color.
Some celebrities known for their green eyes include Angelina Jolie, Amy Adams, Justin Timberlake, and Ryan Gosling. Other eye colors, such as amber and violet, are considered to be even rarer.
Are GREY eyes the rarest?
No, grey eyes are not the rarest eye color. In fact, according to the American Academy of Ophthalmology, the most common eye color worldwide is brown, with an estimated 55% to 79% of the world’s population having brown eyes.
Blue is the second most common eye color, found in 8% to 10% of the world’s population.
Green is the third most common eye color, with an estimated 2% to 5% of the world’s population having green eyes. Grey eyes are the fourth most common eye color, estimated at 1% to 3% of the world’s population.
Amber, hazel, and grayish-brown are all rarer, each estimated at 1% or less of the world’s population. The rarest eye color is said to be red, due to a low amount of melanin.
Do purple eyes exist?
No, purple eyes do not exist. This is because the coloring of our eyes is determined by the amount of melanin (pigment) in our iris. The amount of melanin present in the iris can vary from person to person, and can create an array of eye colors from light blue to dark brown.
However, the spectrum of natural eye colors does not include purple. Therefore, it is not possible for someone to have purple eyes, though someone may appear to have purple eyes depending on lighting, clothing, and other factors.
Can 2 blue eyed parents have a brown eyed child?
Yes, it is possible for two blue-eyed parents to have a brown-eyed child. This is due to a genetic phenomenon known as incomplete dominance. This phenomenon occurs when neither of the two alleles (or gene variants) for a trait is completely dominant over the other.
In the case of eye color, brown is dominant over blue. This means that if one parent has a blue allele and the other has a brown allele, there is a chance that their child can have brown eyes; however, there is no guarantee as this is determined by the random assortment of chromosomes during ovulation.
Additionally, an individual may be heterozygous for eye color, meaning that they possess one allele for blue and one allele for brown. In this case, the individual will have brown eyes because brown is dominant to blue.
Are there only 2 true eye colors?
No, there are not only 2 true eye colors. Depending on the amount of melanin present in the iris and other genetic factors, eye color can range from black, brown, blue, gray, green and hazel. Eye color is a polygenic trait, meaning that it is determined by the combined effect of several different genes.
Additionally, eye color can be affected by environmental factors, particularly in children. For example, babies born with very light eyes may become darker as they age if exposed to more sunlight than usual.
Are brown eyes rare?
No, brown eyes are not particularly rare. Brown eyes are the most common eye color throughout the world, with an estimated 79% of the world’s population having brown eyes. Blue eyes are the second most common eye color, followed by amber, gray, green, and hazel.
Brown has traditionally been the most frequent eye color as a result of it having the highest amount of melanin. Generally speaking, the genetics that determine eye color are inherited in a dominant/recessive pattern, so if both parents had brown eyes, those are the most likely eyes for their children to have.
What eye color is the rarest?
The rarest eye color is green, which is found in only 2% of the global population. Green eyes vary in shade from light green to dark olive, and are most commonly found in Europe and parts of Asia. Green eyes are a result of a small amount of pigment called melanin on the front layer of the iris, which scatters light and gives a unique hue to the eye color.
Certain shades of green may also be found in parts of Africa, the Middle East, South America, and looking to incoming migrations, it is possible to find green eyes in other parts of the world too.
Can 2 brown-eyed people have a blue eyed baby?
Yes, two brown-eyed people can have a blue-eyed baby. This is because eye color is determined by genes, and although they may both have brown eyes, they could still be carriers of the gene for blue eyes.
If both parents are carriers, they could each pass the gene on to their child, resulting in a blue-eyed baby. Depending on the genetics, the blue-eyed trait may be a dominant gene, meaning that even if only one of the parents is a carrier, the baby can still have blue eyes.
In any case, it is important to remember that eye color is not determined solely by the parents’ visible eye colors. Eye color can change from the color the baby is born with, and even if two parents have brown eyes, their baby could still have blue eyes.
Do people have 2 eye colors?
In general, no, people do not have two eye colors. Most humans have eyes with only one color – either brown, blue, hazel, green, grey, or variations thereof. The rarest eye colors are amber, red, and violet.
It is possible for a person to appear to have two colors in their eyes, due to a condition called heterochromia. This is a result of pigment differences in the iris of the eyes, meaning that each eye can have a different color.
This can be the result of genetic mutations or injuries. Individuals with complete heterochromia will have one eye that is a darker color, while the other will be a lighter color. This is a very rare condition, and occurs in fewer than 200 people worldwide.
What color catches the eye first?
The answer to what color catches the eye first really depends on the context. Generally, people are drawn to brighter and more vibrant colors like red, yellow, and orange due to our evolutionary responses to danger and potential food sources.
However, studies on color psychology have found that certain colors can have deeper emotional and psychological effects. For instance, blue typically invokes feelings of tranquility and serenity and is often perceived to be calming, whereas red can evoke feelings of energy and excitement.
Various other factors like saturation, value, and hue can also determine which color catches the eye first. Ultimately, the color that catches the eye first is determined by context, personal preference, and subconscious biases.
What color eyes have worse vision?
In fact, eye color does not typically have any effect on a person’s vision or ability to clearly see their surroundings. However, some people may experience different eye conditions (such as certain forms of color blindness) that can cause vision problems, regardless of their eye color.
Additionally, certain pigmentation disorders can lead to vision problems, regardless of eye color. Also, studies have found that non-brown eye colors may be more likely to carry certain gene mutations related to vision problems.
So while certain conditions may be more common in individuals with non-brown eye colors, no eye color is generally considered to have worse vision.
