The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive.
While blue eyes are more sensitive to light during the day, people with blue eyes tend to see better at night – unless there are bright lights.
The vast majority of people in the world have brown eyes. The second most common color is blue, but people can also have green, gray, amber, or red eyes.
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
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. But the fact is that a small (albeit very small) percentage of people are indeed born with purple eyes.
Are Purple Eyes Rare? True purple eyes are exceedingly rare. Less than 1% of the world's population has them, making them rarer than blue, hazel, amber, grey, or green.
Although the traditional blue-eyed allele is rare in Asian populations, there are still a considerable number of people who have it.
"In Australians of European ancestry, the percentage of eye colours are 45 percent blue-grey, 30 percent green-hazel and 25 percent brown. If you're considering non-European ancestry it is the almost completely brown eye colour."
Blue eyes also represent innocence and carefree. Brown eyes are a more mature eye color and represent stability, security and strength.
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.
Brown Eyes: 45 percent. Blue Eyes: 27 percent. Hazel Eyes: 18 percent (Note: Hazel eyes consist of shades of brown and green.) Green Eyes: 9 percent.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes. Or green or hazel eyes for that matter.
In most people, the answer is no. Eye color fully matures in infancy and remains the same for life. But in a small percentage of adults, eye color can naturally become either noticeably darker or lighter with age. What determines eye color is the pigment melanin.
It's All About Structure. The structure of the eye orbits, otherwise known as the bones around your eye, are directly linked to the attractiveness of your eyes. An orbiture with a bigger height and width is seen as more attractive than a smaller or thinner one.
People who had deep brown eyes during their youth and adulthood may experience a lightening of their eye pigment as they enter middle age, giving them hazel eyes. Conversely, someone born with hazel eyes might see their irises get darker as they grow older.
Rarest Eye Colour – Green.
What eye colors are acceptable for Aussies? Both the ASCA and AKC standards are virtually identical, stating that eyes shall be brown, blue, amber or any covers pretty much variation or combination of these with marbling and flecks acceptable which anything you are likely to see in a dog.
Australians of European ancestry have about 25 percent brown eyes while those of non-European descent almost all have brown eyes. If you include hazel eyes (sometimes called hazel brown eyes), the prevalence is even higher. This high prevalence doesn't mean all brown eyes look the same.
The most common eye colors depend largely on geographic location. For example, Asians typically have brown eyes, while Europeans are more likely to have eyes of blue or other lighter hues.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
In Asia, red hair can be found among some peoples of Afghan, Arab, Iranian, East Indians, Mongolian, Turkic, Miao, and Hmong descent.
Amber eyes are extremely rare. Most sources say that only about 5% of people have true amber eyes. Coming up with a hard and fast number or percentage, though, is not as easy as you might think—there simply haven't been enough large-scale studies done to quantify eye color prevalence with certainty.
Legendary actress Elizabeth Taylor's eyes were famous for being stunningly beautiful and distinct. Widely known for having the most striking eyes in Hollywood, Taylor had what appeared to be rare natural purple eyes.
Silver (grey) eyes: A grey-silver colour is quite rare and occurs as a result of virtually no melanin in the iris. Silver eyes are considered to be one of the rarest colours around the world, but when they do occur, this is most often seen in eastern Europe areas.
