Scientists believe, therefore, that everyone with blue eyes today can be traced back to one ancestor who had that genetic mutation. While the MC1R gene is the dominant decider of hair color, it isn’t the only one. According to a 2018 study published in Nature, the OCA2 gene, which is important for eye color, also interacts with the MC1R gene and can reduce your likelihood of having red hair.
Hair Color For Green Eyes And Fair Skin Tone
Green eyes are rare, but so are blue eyes, red hair is even rarer compared to straight blondes. A review by medical daily explains that these two traits are recessive genes, therefore, reducing the number of individuals to extremely low. Red hair is caused by a recessive gene, while green eye color is recessive to brown but dominant to blue. Thus, the chances of getting red hair and green eyes are e quite rare. If one parent passes on the dominant brown eye gene, the child will not get the green eyes.
Truly special people: green eyes and red hair - how rare is this combination?
Based on this fact, you might see more green and blue eyes in this region than brown eyes, which are linked to more dominant genes. However, this doesn’t mean all people from Scandinavia have lighter eyes. Red hair and green eye genes are simply not as common in populations as other hair and eye colors.
Map of red hair frequency in Europe
The same study, however, found that the four other alleles are not of Neanderthal origin [31]. 40,000 BP, the scenario of Neanderthal introgression makes sense for Val92Met, which is found throughout Eurasia. However, the other loss-of-function alleles, which are more specific to northern Europe, probably originated in modern humans. Recessive genes that dictate lighter eye color are the most common in Scandinavia (Denmark, Finland, Iceland, Norway, Sweden). In this region, we can see more people with green and blue eyes than with brown, which are related to dominant genes, which again does not mean that all Scandinavians have lighter eyes. There are other shades of eye color out there that haven’t yet been matched with the right hair color.
Can Eye Color Change With Age?
A review from 2015 suggests people with darker eyes may have a reduced risk of hearing loss not related to age. Gray eyes may contain just enough melanin in the front layer to dim the blue wavelengths of light that are reflected back by the tissue of the eye. Dark gray eyes have a bit more melanin in the front layer than pale gray eyes.

Red hair with blue eyes is the rarest combination of eye and hair color. A Chinese village called Liqian has a surprisingly high concentration of blond hair and green-eyed people. Two-thirds of its inhabitants have this rare combination of hair and eye color. It is believed that people living in Liqian are descendants of Roman General Marcus Crassus’s army that went missing, and they got this unique combination of eyes and hair color from their ancestry. You might think eye color is pretty intuitive, depending on where your family is from. "Eye color is an interesting report that we have," Lehman says.
How Rare Is It to Have Red Hair and Green Eyes?
Interestingly, the lack of melanin also puts redheads at a higher risk for skin cancer. If both parents carry the gene but do not have red hair, the chances of their children getting red hair is around 25%. Scotland also has the highest concentration of green-eyed people. Ireland also has a significant number of green-eyed people. As a result, the highest number of green-eyed and red hair people can be found in the northern and western parts of Europe.
Other Rare Combinations
The fact that red and green are complementary colors also makes for a visually striking appearance. Therefore, this trope is used as an easy way to distinguish an important, notable character visually. Southwest Norway may well be the clue to the origin of red hair. It is now almost certain that native Irish and Scottish Celts were taken (probably as slaves) to southwest Norway by the Vikings, and that they increased the frequency of red hair there. It is hard to calculate the exact percentage of the population having red hair as it depends on how wide a definition one adopts.
Changing Your Eye Color With Contacts
In most cases, you’d have blue eyes and hair somewhere on the spectrum of blond to brown or red hair with brown, hazel or green eyes. While the odds of having red hair and green eyes depends on a variety of factors, it’s interesting to look at the genetics behind this combination. Just a few of these genes dictate hair color and eye color. There is no one-size-fits-all answer to this question, as the best hair color for green eyes and fair skin will vary depending on your own skin tone and eye color. However, some popular hair colors that are often recommended for people with green eyes and fair skin include light brown, medium brown, auburn, light red, and light copper. What causes this divergent health status in red-haired women?
Girl, boy, dog and background are layered and grouped separately. "They seem to have showed up right around the time when people were leaving Africa," she says. "So they appeared in humans when humans had already made it to Europe." Another trait that 23andMe is looking into is peoples' preference for salty and sweet foods. And, as with their other data, the team figures this out by interviewing research participants.
Hazel-colored eyes characterize a blend of green, orange, and gold. The latest data suggest around 5% of the world’s population have hazel-colored eyes. The people with hazel eyes have less pigment than brown but more than blue. Hazel eyes can be more commonly seen in the people from North Africa, the Middle East, and Brazil.
Eye color is an inherited trait with multiple genes affecting the shade. Genes related to the production of pigments—melanin, eumelanin, and pheomelanin—dictate the color of your skin, hair, and eyes. A person's eye color reflects a unique combination and concentration of pigments in the iris. Red hair and blue eyes is a hard combination to find, actually the rarest combination.
These genes are thought to interact with OCA2 and HERC2 to decide eye color. The combination of pigments, as well as how widely they're spread out and absorbed by the stroma, determine whether an eye looks brown, hazel, green, gray, blue, or a variation of those colors. Heterochromia, although not viewed as a severe disorder, affects many individuals. The disorder is characterized by different-colored irises or different colors within the iris. It is inherited or caused by somatic mutations within the cells.2 In addition, it can be caused by the inactivation of particular genes within the cells.
