Eye color has fascinated people throughout herstory. Myths and legends grew up around the rarer colors gracing the "windows to the soul."
Superstitions embedded in folklore -- such as the link between eye color and certain [psychic] abilities and personality traits -- survive into modern times [like envious green eyes on temperamental redheads], even though we now think that genetics determines eye color.
Scientific advancement has revealed that the genetics behind eye color are more complex than researchers first believed.

- Eye color is a wide spectrum
- If you think you have blue eyes, they're actually brown and you just don't realize it
- [The Buddha (formerly the Scythian Prince Siddhartha Gautama) had the "32 Marks of a Great Man," including the mark of a Dharma wheels on the soles of his feet, long digits, a lion-like torso, sensitive taste buds, evenly spaced white teeth, a very long tongue, long arms that reach his knees, very blue eyes (like ocean sapphire), and a sheath over his sexual organs (S.A. Mattice, 2021). The 29th mark is abhi-nīla-netto, "very blue eyes, like sapphire, eyes deep blue" (R.B. Epstein, 2012). Prince Siddhartha, who became the Buddha (the "Awakened One") at the age of 35, also had the 80 secondary characteristics.]
Approximately 16 genes determine eye color, and genes are influenced by incomplete dominance and epistasis.
"
Epistasis" means that a gene is affected by the expression of one or more additional (modifier) genes. In brief, eye color depends on many different genes and their effects on one another.

Redheads, though rare, are plentiful in media. |
- But I have BLUE eyes! - No, you don't: The appearance of blue, green, and hazel eyes results from the Tyndall scattering of light in the stroma, a phenomenon similar to Rayleigh scattering, which accounts for the false blue color of the sky [5]. Neither blue nor green pigments are present in the human iris or vitreous humour. It's an illusion. More

Every eye has a unique iris pattern that can be photographed and examined for health. |

Human eye colors vary widely, with shades of brown, amber (yellowish), blue, gray, hazel, and green.
Eyes of any color contain the same number of
melanocytes. Variations in the amount, distribution, and type of melanin pigments within melanocytes account for different colors.
