There's a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all. The same Nature study mentioned above found that another gene variant, HERC2, interacts with both the MC1R gene and the OCA2 gene—and it can shut off the redhead gene while expressing blue eyes and blonde hair.
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.
Blue eyes and red hair forms the rarest combo on earth. Most (natural) redheads will have brown eyes, followed by hazel or green shades.
But the red hair and blue eye combination is so unusual because it is the result of two different sets of DNA instructions, or mutations, happening in the same person, according to Elgar.
But here's the thing. Despite its popularity, strawberry blonde hair only occurs naturally in between 1 and 2 percent of the world's total population — which means it takes hair color and technique to make it happen for the rest of us. In fact, it's a hue that's been rare yet in demand for centuries.
The MC1R variant gene that gives people red hair generally results in skin that is difficult or impossible to tan. Because of the natural tanning reaction to the sun's ultraviolet light and high amounts of pheomelanin in the skin, freckles are a common, but not universal, feature of red-haired people.
Irish immigrants arriving in Australia looking for labour gained a reputation as heavy drinkers and fighters, with 'blue' being local slang for a fight. The term evolved to come to mean a redheaded Irishman.
One of the many facts about redheads is that their hair will never turn grey. The pigment in their hair that causes it to be red will just fade over time, causing their hair to turn blonde or white, but never grey.
The rarest hair and eye color combination is red hair with blue eyes, occurring in less than 1% of the global population.
For a recessive trait to be expressed the individual must be pure breeding, hence two red heads can not produce any other colour in a child. If red hair is dominant, the chances are one in four that a child will NOT be a red head if mum and dad are both ginger nuts.
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. While you may not be a natural-born redhead, your colorist can help you achieve your ideal strawberry blonde shade at the salon.
Eye shadow shades for redheads can range from soft neutral browns to green. Deep browns with hints of red, like a brownish-brick red for the crease of the eye works well for redheads. A neutral tan can be placed on the lids or under the brow as a highlighter.

Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
Fun Fact: Redheads tend to have thinner enamel than other people, and so the inner layer of dentin is more visible and appears more yellow.
Redheads feel hot and cold temperatures more severely than anyone else. In 2005, the University of Louisville discovered this hidden gift and hypothesised that the redhead gene, MC1R may cause the human temperature-detecting gene to become over-activated, making redheads more sensitive to thermal extremes.
Colliss Harvey's research found that redheaded individuals have higher levels of vitamin D, which is a source of strength.
Bluey is an Australian nickname for a person with red hair. As a nickname, Bluey may refer to: Frank 'Bluey' Adams (born 1935), former Australian rules football player.
Bluey is an Australian animated preschool television series which premiered on ABC Kids on 1 October 2018. The program was created by Joe Brumm and is produced by Queensland-based company Ludo Studio.
Aussie Word of the Week
A blue is a fight, dispute or row. You can bung on a blue, stack on a blue or turn on a blue. The slang word has been around since the 1940s and is used to refer to everything from fisticuffs at the pub to a brawl on the footy field.
Is all red hair caused by albinism? Well, no. The red hair seen in people with European ancestry is caused by a mutation in a gene called MC1R. MC1R is involved in determining the balance of two variations of melanin in the body.
The skin of a redhead is thinner compared to others and is derived from the ectoderm. Teeth enamel is also derived from the ectoderm and thus is thinner than usual. Since the enamel coating is thin, the inner layer of tooth-dentin is more visible and offers a yellowish appearance.
