Human eyes can come in a variety of colors, including brown, green, blue, hazel, gray, and amber. Eye color is determined by the amount and types of pigment in the iris of the eye. Brown eyes are the most common, but even within the “brown eyes” category, shade and hue varies.
Blue eyes are less common than brown, and can range in hue from faded to vibrant. Green eyes are less common than blue, and often contain some shades of brown or yellow. Hazel eyes combine shades of brown, green, gray, and yellow and may change color based on what the person is wearing or the lighting around them.
Gray eyes range from a light shade of gray, to almost black in color. Amber eyes are the rarest type, and may contain hints of copper or yellow.
The color of a person’s eyes, like other skin and hair characteristics, is determined by various genes passed down from their parent’s gene pool. Rare, heterozygous combinations can result in unexpected eye colors that are extremely difficult to predict.
For example, some people may have hazel eyes that contain more green hues instead of the typical brown less common combinations include purple, aqua (sometimes known as blue-green) and red. While some of these colors may be the result of wearing colored contacts, it is also possible for a person to have these eye colors naturally.

What is the rarest eye color for humans?
The rarest eye color for humans is amber. In many parts of the world, including the United States, amber eye color is considered a very rare occurrence. While estimates vary, it is thought that only around 5% of the world’s population has amber eyes.
This is due to a lack of a specific gene mutation in the OCA2 and HERC2 genes which are responsible for the production of melanin. In addition, amber eyes are only seen in a handful of other species including some species of birds, fish, and reptiles.
Do purple eyes exist?
No, human eyes do not naturally occur in the color purple. Although there are some medical conditions that can change the color of the eyes temporarily, there are no known medical or genetic conditions that will permanently change the eye color to purple.
However, certain theatrical and costume contact lenses are available that can temporarily change the color of one’s eyes to purple. These lenses can be purchased at costume and novelty stores, however it’s important to remember that improperly used contacts can cause eye infections and other issues, so be sure to use them only under the care and instruction of an eye care professional.
Are grey eyes the rarest?
No, grey eyes are not the rarest eye color. In fact, they are the most common eye color in the world. Approximately 55-79% of the world’s population have eyes that are shades of brown, whereas grey eyes preferred by only about 2-5% of the world’s population.
Blue eyes, on the other hand, are the rarest, being preferred by only 1-2% of the world’s population. Green eyes, while rarer than brown eyes, still slightly outnumber those with grey eyes at 2-17% of the world’s population.
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 these genes come in pairs of alleles — one from each parent. It’s possible for two brown-eyed parents to have an allele pair that codes for blue eyes and pass this on to their child.
In this case, one parent could have two dominant brown-eye alleles, and the other could have one dominant brown-eye and one recessive blue-eye allele. In this instance, the baby would be born with blue eyes.
This phenomenon is known as genetic recombination or genetic shuffling, because the allele combinations seen in the offspring are different from those seen in the parents.
Interestingly, even if a child is born with blue eyes, it doesn’s mean that all of their siblings will also have blue eyes. Eye color is a complex trait, and genetics determine more than just whether someone has blue or brown eyes — variations in color, how dark the eyes are, and other features are also determined by genetics in a variety of ways.
Are there only 2 true eye colors?
No, there are not only two true eye colors. In fact, there are many different types of eye colors ranging from blue to brown to hazel and more. Some eye colors are best described as a combination of two or more colors, such as “amber” which is a combination of yellow, orange and brown.
Other more rare eye colors include red, purple, and the elusive grey. While the most common eye colors are blue, brown, and hazel, there are many variations of these and even some that are more difficult to spot.
Ultimately, each person’s eye color is unique and is determined by the amount and type of melanin in their iris.
Are GREY eyes blue or green?
The answer to this question is that grey eyes are neither blue nor green. Rather, grey eyes are a combination of different colors that appear to be grey. It is speculated that grey eyes contain a combination of colors such as yellow, blue, green, and even light brown, depending on the individual’s eye color and surrounding lighting.
Additionally, the shade of grey in the eye can vary from light to dark, making grey eyes one of the more challenging eye colors to identify.
Do people have 2 eye colors?
No, people generally do not have two eye colors. While two different color eyes, known as “heterochromia,” is uncommon but not unheard of, it is typically rare for both eyes to actually contain two separate colors.
It can occur in humans, but it is more common in animals. In humans, the best-known example of heterochromia is the condition called “sectoral heterochromia,” in which someone has one eye with two different colors.
Additionally, some may have a condition known as “complete heterochromia,” in which both eyes have different colors. However, this is quite rare. Generally, a person’s eyes are the same color, although the shade may vary.
Can eyes change color?
Yes, eyes can change color. This usually happens slowly over time and is more likely to occur with lighter eyes. How much a person’s eye color changes depends on the original color of their eyes and the influence of external factors like age, environment, and health.
Eye color is determined by the amount of melanin in the front part of the iris. A rise in melanin can make the eyes appear darker while a decrease can make them look lighter. Multiple genes can determine the amount of melanin produced, but the exact workings of it are still a mystery.
One potential cause of eye color change is a disease/condition called heterochromia iridis, where someone has two different colored irises. People may inherit this condition or it can be caused by disease or trauma.
In other cases, a person’s eyes can become two different shades due to the use of certain medications or contact lenses.
Eye color is also known to change with age. Research suggests that babies tend to have lighter eyes than adults, and as people get older, their eyes may start to darken progressively. Pregnancy, UV exposure, and stress can also cause eye color changes.
All in all, eye color can change depending on various factors, but it is most likely to occur in lighter eyes.
Did Elizabeth Taylor have violet eyes?
Yes, Elizabeth Taylor was known for her iconic violet eyes. Her violet eyes were natural, and debuted in National Velvet when she was just a young girl. She was born with blue eyes, but after a case of childhood pneumonia, her eyes changed to a bright violet hue.
Her eyes were so unique and beautiful that fans and admirers around the world instantly noticed. Throughout her career as an actress and world-renowned beauty, Elizabeth Taylor’s violet eyes were the first thing that people commentated on.
In addition, her violet eyes played a major part in her success as a film star. They contributed to her ability to command the attention of a room whenever she entered it, and make a lasting impact on every film that she starred in.
Her violet eyes were so famous that they were frequently referred to as her most famous feature. Elizabeth Taylor’s violet eyes are remembered to this day as an iconic part of her beauty and her success.
What eye colors do not exist?
No eye colors that exist in nature do not exist, as all colors of the visible spectrum and beyond can be found in the eyes of living creatures. However, there are some mutations which can lead to eye colors that are unnatural or unusual, such as the genetic mutations which lead to eyes that are completely red or completely turquoise in color.
These colors are not technically “eye colors”, as they come from a mutation rather than existing in the natural world. Certain kinds of unnatural contact lenses have been developed which can create eye colors such as purple or green, but these are not true eye colors either.
Overall, any color that does not occur naturally in nature does not exist as an eye color.
Can humans have black eyes?
Yes, humans can have black eyes. Referred to as “black eyes” or “midnight eyes,” they are actually extremely dark shades of brown. Genetics determine human eye color and certain combinations of genes can produce a variety of shades including extremely dark brown, or nearly black, eyes.
Some individuals are born with very dark eyes and they may appear to be black, though in most cases the color deepens with age. Certain racial groups, such as people of Asian, Middle Eastern and African descent, are more likely to have naturally dark brown, or even black eyes.
This type of eye color is relatively rare in the United States and Europe.
Can a person have naturally red eyes?
Yes, it is possible for a person to have naturally red eyes. Red eyes occur when there is an absence of pigment in the iris, a part of the eye that controls how much light enters the eye. People who have red eyes usually have a rare genetic condition known as albinism that prevents the body from producing melanin pigment, resulting in the red eye color.
Additionally, some people can have naturally red eyes caused by genetic mutation, but this is extremely rare. Red eye color can also be caused by certain medications, such as high-blood pressure or antidepressant medications, or by exposure to bright lights.
In these cases, the red-eye color resolves once the medications or light exposure stops.
How rare are red eyes in humans?
Red eyes in humans are quite rare. The condition is known as albinism and generally affects less than one percent of the population worldwide. Albinism is typically caused by a congenital disorder where the body does not produce enough melanin, the pigment that gives color to our skin, hair, and eyes.
People with albinism often have pink or red-tinted eyes because there is no pigment to absorb and scatter the incoming light in the iris. Red eyes in humans can also be caused by a mutation in the OCA2 gene, which is responsible for the production of melanin.
The condition usually affects only one eye and is typically accompanied by pale skin and hair.
Can human eyes glow red?
No, it is not possible for human eyes to glow red under normal circumstances because humans do not have a special organ like some animals that produces and emits light. However, there are certain conditions in which the eyes may appear to have a faint red color.
This can happen when a person has Heterochromia, a condition where the eyes are different colors. In this case, one eye can appear to be a slightly reddish hue. Also, if a person is reflecting light from a red source in a dark room, the eyes may appear to be a faint red as well.
In both cases, the eyes are not actually producing light and the red color is not visible under normal lighting.
