Most (natural) redheads will have brown eyes, followed by hazel or green shades.
Rarest kind of redhead
Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
Red Hair And Blue Eyes Is Rare
Red hair occurs naturally in one to two percent of the human population, while just 17 percent of the world's population has blue eyes. The majority of redheads have brown, hazel, or green eyes.
“Red hair and blue eyes are both recessive traits which means a person needs to inherit both of the genes for red hair and blue eyes, from both parents. In contrast, brown hair and brown eyes are dominant traits, which is why they are much more prevalent.”
Less than 2 percent of the world's population has red hair, making it the rarest hair color in the world. It's the result of the mutated MC1R gene. If both parents carry that gene, their child has a 25% chance of getting lovely, red locks, even if the parents don't have red hair themselves.
Research indicates that redheads have higher thresholds for pain and need less vitamin D than the rest of us thanks to the MC1R gene mutation, which gives their hair its hue.
About 1–2% of people of European origin have red hair. Especially female redheads are known to suffer higher pain sensitivity and higher incidence of some disorders, including skin cancer, Parkinson's disease and endometriosis.
Redheads probably won't go grey. That's because the pigment just fades over time. So they will probably go blonde and even white, but not grey.
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.
The MC1R gene might actually make redheads look young
According to research published in Current Biology, people with the MC1R gene, aka the gene that produces red hair and fair skin, tend to look several years younger than their non-ginger counterparts.

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.
'It's extremely rare for people to have hair that is naturally a strawberry blonde color. Basically, strawberry blonde is mostly based on red tones, with blonde highlights dotted here and there. It takes its name from the Italian renaissance.
Previous studies had shown that redheads inherit two versions of the MC1R gene that leads to red hair – one from their mum and one from their dad. Although almost everyone with red hair has two copies of the red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.
Research has shown that people with red hair perceive pain differently than others. They may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications. However, studies suggest that their general pain tolerance may be higher.
Why do people sometimes appear to be younger than others of the same age? The culprit turns out to be an innocent-sounding gene, MC1R, responsible for producing, among other things, locks of fetching red hair as well as pale skin, researchers have discovered.

One study shows that, contrary to popular belief, redheads are not weaker than blondes or brunettes. After studying the effect of pain in humans, researchers found that redheads appear to be "better protected" on the surface level.
Lifespan: up to 20 years in captivity, 5-10 years in the wild.
Some studies indicate that redheads are more prone to illness because they prefer to keep out of the sun and so lack vitamin D, or because their ability to absorb the vitamin is less efficient.
Naturally Produce More Vitamin D
Per a study published in 2020 in Experimental Dermatology, redheads are more efficient at synthesizing vitamin D. The vitamin is crucial for bone health and may protect against depression and fight off colds.
They are typified as impulsive, quick-tempered, libidinous, and wild. The personalities of people with red hair are often believed to be imitative of their red hair, and they are seen as fiery, hot-tempered, hot-blooded, passionate, and angry.
And the statistics bear that stereotype out. Ireland has the highest per capita percentage of redheads in the world -- anywhere from 10 to 30 percent, according to Eupedia, a website that explores European genetics and ancestry.
