In the past, we believed that a person's eye color was determined by a single gene that expressed as brown (a dominant gene) or blue (a recessive gene). But this is no longer true.
Genetic research has revealed that eye color is a complex expression of over 60 genes. These genes create subtle differences that can vary even between people with the same eye color, making a person's eye color unique to their DNA.
Some of the world's most common eye colors are blue and brown, which represent two of the six basic colors in the RGB spectrum. The rest of the colors are rare variations of these primary hues.
Most people have brown eyes, which are the most common of all human eye colors. This is the result of several different gene groupings that produce the pigment melanin, which darkens the eye.
Red is another of the most common colors. It is associated with royalty and passion. This makes it an appealing choice for most men.
Pink, on the other hand, is strongly associated with femininity and softness. It can evoke feelings of happiness and love, making it a great choice for women in many types of situations.
Yellow is also a popular choice, especially for bright and sunny products. However, this color can be a bit of an eye irritant when used in large quantities, so it is best avoided in areas where attention is needed for critical tasks like computer screens or classrooms.
