Albinism: People who have an inherited condition called albinism have little or no melanin in their eyes, hair and skin. People with albinism usually have eyes that are very light blue. Rarely, they have pink or red eyes. Without melanin, their irises are clear, which makes blood vessels inside the eye visible.
Red/Pink Eyes
Two major conditions cause a red or pinkish eye color: albinism and blood leaking into the iris. Although albinos tend to have very, very light blue eyes due to a lack of pigment, some forms of albinism can cause eyes to appear red or pink. Amber eyes are a beautiful honey color!
Of the less common eye colors, pink and red eyes are considered to be the most unique in the world, giving new meaning to the word “rare.” Only one in every 20,000 people have a form of albinism, according to the National Institutes of Health, and even fewer have red-tinted eyes.
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. And while violet eyes are a rarity, they're really just a blue hue, with light bouncing off the surroundings and turning the eyes violet.
Did Elizabeth Taylor Really Have Purple Eyes? This is a popular myth. Elizabeth Taylor's eyes appeared purple in some photos due to lighting, makeup, and clothing. In reality, her eyes were blue, which can be seen in the vast majority of her photos.

Albinism. Albinism is a genetic condition that causes a reduced amount of melanin in a person's body. It often includes reduced melanin in the eyes. With very low melanin levels in the eye, the iris might appear blue or, in some instances, red or violet.
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.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich brown eyes.
Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide. Black is not an eye color. While some eyes may look black, they're either just a very dark brown or have large pupils (more on this below).
The least common birthdays in the U.S. interestingly all hover around major holidays. December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common.
People with albinism usually have eyes that are very light blue. Rarely, they have pink or red eyes. Without melanin, their irises are clear, which makes blood vessels inside the eye visible. The blood vessels give eyes their pink or red color.
In many cases, red eyes aren't dangerous and may not even need treatment. However, there are conditions that cause red eyes that can be more serious. If your eye redness lasts longer than a day or two, or if your young child has red eyes, you should contact your healthcare provider.
Perhaps the rarest eye color is not one color at all, but multicolored eyes. This condition is called heterochromia iridis. A person can be born with this condition, it can develop in infancy, or it can develop as a symptom of a systemic disease or after an injury to the eye.
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. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland.
Brown eyes, on the other hand, are the most common eye color, yet respondents to the study found them to be the least attractive. The possibility of altering the color of one's eyes from brown to hazel with the use of safe laser eye color alteration surgery is no longer a pipe dream.

The world of eye color rareness is a fascinating one, with green, amber, gray, hazel, and violet or red eyes being the rarest of them all. These unique colors are a result of a complex interplay between genetic factors and the presence of pigments like melanin or lipochrome in the iris.
The white portion of the eye (sclera) can appear red when the vessels on the surface become enlarged. This may result from mechanical irritation, environmental irritants (such as extremely dry air, excess sun exposure), allergic reactions, infection, and other medical conditions.
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 irises.
Amber eyes: A golden yellow or copper colour occurs due to higher quantities of the pigment lipochrome (yellow pigment) and very little melanin, and are considered very rare. Amber-coloured eyes are most often seen in Asian and South American areas of the world.
Permanent changes to eye color can be achieved through iris implant surgery, corneal pigmentation, and laser eye color change. Iris Implant Surgery is a procedure that inserts a prosthetic iris into the eye. It was originally developed to treat iris defects such as albinism and aniridia.
A black eye develops when fluids collect in the tissues around the eye. The bruising and blue and purple discolouration are caused by broken blood vessels under the skin. These tissues will usually be swollen too. The eye itself is not usually damaged.
