People with green eyes are curious about nature, very passionate in their relationships with other people and have an overall positive and creative outlook on life. These people tend to get jealous easily, but possess large amounts of love. Hazel eyes– hazel eyes are a mixture of colors, but mostly green and brown.
How do you get green eyes genetics?
Green eyes can seemingly pop up out of nowhere because they are recessive to brown eyes. And because green eyes are determined by a separate gene. *In genetics lingo, we say that brown is dominant over blue and green. And that green is recessive to brown but dominant over blue.
Are green eyes attractive?
The conclusion: Green eyes are considered attractive because it's a rare color. Common eye colors like brown, blue, even black, are typically seen all around because of its pigmentation.
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.

Irises are classified as being one of six colors: amber, blue, brown, gray, green, hazel, or red. Often confused with hazel eyes, amber eyes tend to be a solid golden or copper color without flecks of blue or green typical of hazel eyes. Blue eyes have a low level of pigment present in the iris.
Hazel eyes are due to a combination of Rayleigh scattering and a moderate amount of melanin in the iris' anterior border layer. Hazel eyes often appear to shift in color from a brown to a green. Although hazel mostly consists of brown and green, the dominant color in the eye can either be brown/gold or green.
People with eyes that are so dark brown, they sometimes appear black have one of the rarest eye colors. As such, they are often perceived as mysterious or secretive, yet a study in Current Psychology reported by Medical Daily showed that people with darker eyes are generally seen as more agreeable.
Blond (male), blonde (female), or fair hair, is a hair color characterized by low levels of the dark pigment eumelanin. The resultant visible hue depends on various factors, but always has some sort of yellowish color.
Eyes with a bit more melanin are green, hazel or light brown. And those with a high concentration of melanin are medium or dark brown. But within 12 to 18 months, more melanin can accumulate in the iris, causing eye color to change from blue to green, hazel or brown.
Some people have albinism disease which may be a small amount or no pigment melanin in the iris and it turns out that they have purple eyes. Sometimes if blue eyes people's eyes got injured by sun it may caused appearance of blood vessels and they might end up having purple looking eyes.
Red eye is caused by swollen or dilated blood vessels on the sclera, the white outer surface of the eye. Red eyes can occur in one or both eyes and may be accompanied by eye pain, itching, eye discharge, swollen eyes or visual disturbances such as blurry vision.

How does eye color work? Eye color comes from a combination of two black and yellow pigments called melanin in the iris of your eye. However, because many genes are required to make each of the yellow and black pigments, there is a way called genetic compensation to get brown or green eyes from blue-eyed parents.
Until proven otherwise, your yellow eyes are a sign that you have elevated levels of bilirubin in the blood called jaundice. Jaundice is a sign of many possible liver problems that can cause it to function incorrectly. Alcoholism most commonly causes cirrhosis (scarring of the liver).
It is now clear that eye color is a polygenic trait, meaning it is determined by multiple genes. Among the genes that affect eye color, OCA2 and HERC2 stand out. Both are located on human chromosome 15. The OCA2 gene produces a cell membrane transporter of tyrosine, a precursor of melanin.
If you received a blue allele and a brown allele, your eye color would be brown because brown is the dominant allele. If you have blue eyes, that means you received blue alleles from both parents. Your genes also determine your eye color by dictating how much (and where) melanin is produced in your iris.
What we know about genes, is that there are two forms of a gene that you can have, dominant or recessive. For each gene, you inherit one form that came from your father and one that came from your mother. Height may not be governed by a single gene, but may be the result of many different combination of genes.
So for hair type, CC gives curly, Cs gives wavy and ss gives straight hair. That is because the curly headed parents, CC, can only contribute a C gene and the straight haired parent, only an s gene. That means all the kids will be Cs and have wavy hair.
Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child. Genetics is so much fun! Two of the most important genes in eye color are OCA2 and HERC2.
The way geneticists represent these two different versions of this eye color gene are B for brown and b for blue (the capital letter is always the dominant, the lowercase, the recessive). So you will have brown eyes with either BB or Bb and blue eyes with bb.
A brown eyed dad and a green eyed mom can have a blue eyed child because there are at least two eye color genes. Because of this, it is possible for both green and brown eyed parents to be carriers for blue eyes. The other odd thing is that the recessive forms of both genes are blue.
