I have never seen people with orange eyes, but they may exist in this world. Some people may get orange eyes, but they are not born with this eye color, they achieve this by wear colored contact lenses. Human eye color is determined by 6 genes which control the amount of melanin in your body. The Melanin decides the color of your eye, hair and skin. Genetic mutations can happen, which give people orange, purple, or other rare eye colors can happen. Besides, since light condition counts in the eye color, some eye colors such as amber can look orange in a brighter environment. Orange eyes may appear as a rare variant of brown eyes.
