There's a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all.
And when you meet a red head with blue eyes, you are looking at the rarest colour combination of all for human beings. Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent.
Green irises (the rarest eye color) have less melanin than brown eyes but more than blue eyes, for instance. “Brown is on one end, blue on the other, and hazel and green are in between,” Dr. Patel says.
Black hair and blue eyes is a much more rare combination than is blonde hair and blue eyes. The reason why these two traits are linked is that the genes responsible for hair and eye color happen to be close together on the same chromosomes.
Are They Rare? Grey eyes are one of the rarest eye colors. Less than 3% of the global population has grey eyes. They're most commonly found in people of Northern and Eastern European ancestry.
Close to 3% of the world's population have gray eyes. People with gray eyes have little or no melanin in their irises, but they have more collagen in a part of the eye called the stroma. The light scatters off the collagen in a way that makes the eyes appear gray.
Unbelievable as it may seem, the answer is yes—natural purple eyes do exist. Purple eyes are also commonly referred to as “violet eyes,” as they are typically a light shade. For most people, this striking eye color can only be achieved with the help of colored contacts.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
How Rare Is Dirty Blonde Hair? About 2 percent of the population are natural blondes, but it's a very popular hair color because many turn to hair dye to achieve it. Brighter blonde shades like ashy blonde and beige blonde are more popular choices than dirty blonde, so you can consider dirty blonde a bit more unique.
#BLONDE! The contest for the most attractive hair colour is obviously won by the blonde color with 35% of the overall vote, followed by the brunette. The bronze goes to Pippi Longstocking (people 30 and above will understand ? ). And the fourth place is for black hair colour.
How common is strawberry blonde hair? Having natural red hair is rare (like, two percent of the population rare), so coming across someone with natural strawberry blonde hair isn't common.
There's a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all.
Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type.
Now you know what is the most common hair colour in the world, but what about the rarest? The rarest natural hair colour is red, which makes up only one to two percent of the global population.
And what would you think is the most attractive eye color? In a website poll of over 66,000 respondents, 20% said green was the most attractive, followed by hazel and light blue at 16%. Brown was far and away voted the least attractive (6%).
Scientists at the University of Louisville, Kentucky, have apparently found a hitherto unobserved link between eye-colour and levels of intelligence. Blue-eyed people, they claim, are more studious, more strategic, more focused, and thus out-perform brown-eyed people in exams.
While some people may appear to have irises that are black, they don't technically exist. People with black-colored eyes instead have very dark brown eyes that are almost indistinguishable from the pupil.
Red or Violet Eyes
Violet and red are unique eye colors caused by an iris with little to no pigment. When light reflects off of the blood vessels in eyes that lack typical pigmentation, the eyes appear violet or red. Astonishing as it may seem, these eye colors occur naturally—and are extremely rare.
Though common in some breeds of cats, dogs, cattle and horses due to inbreeding, heterochromia is uncommon in humans, affecting fewer than 200,000 people in the United States, and is not associated with lack of genetic diversity.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body. Albinism affects 1 in every 3,000 to 20,000 people. What is this? People with albinism usually have very pale or colorless skin, hair, and eyes.
If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation. However, since eye color is polygenic, several other genes exert their effects as well.
Changes in eye color are rare. Sometimes, the color of your eye may appear to change when your pupils dilate. The colors in your environment, including lighting and your clothes, can give the illusion of eye color change.
