Floaters What causes eye floaters? Eye colors are more than what you see. Here we present the causes, prevalence and science behind some of the rarest and most unique eye colors on Earth. A person with differently colored eyes or eyes that are more than one color has heterochromia.
about the symptoms, types, risk factors, causes, diagnosis, and treatment. Heterochromia of the eye is called heterochromia iridum (heterochromia between the two eyes) or heterochromia iridis (heterochromia within one eye). It can be complete, sectoral, or central.
In complete heterochromia, one iris is a different color from the other. In sectoral heterochromia, part of one iris is a different color from its remainder. Heterochromia, or more specifically heterochromia iridum, is a condition where an individual has different coloured eyes or different colours within the same eye.
This captivating trait affects less than 1% of the population, making it a rare and often striking feature. Some cases of heterochromia, known as congenital heterochromia, cause different colored eyes as the result of a benign genetic mutation that affects the development of melanin, or pigment, in the irises. In such a case, you're born with different colored eyes, but it doesn't affect your overall health, including your eye health.
In normal eyes, melanin is distributed evenly which results in a solid iris color be it brown, blue, green etc. Rainbow eyes occur when something goes wrong with melanin production and distribution causing certain areas of the iris to over or under produce pigment. Heterochromia describes when a person's eyes aren't the same color.

Human eye color is fundamentally limited by the pigments melanin and pheomelanin, along with light scattering and absorption.
These mechanisms produce colors from light blue to dark brown, with variations like green and hazel, but cannot.
