Hello, I'm an expert in human genetics and biology. When it comes to eye color, it's determined by variations in a person's genetic makeup, specifically the genes that influence the production of melanin, the pigment that gives color to our eyes, hair, and skin.

Now, to answer your question: Is Gray an eye color?

Yes, gray is indeed an eye color. It is a rare and unique eye color that is the result of a lower amount of melanin in the iris compared to brown eyes, but more than what is found in blue eyes. This reduced melanin allows more light to scatter in the iris, which can create the appearance of a gray or silver color. Gray eyes are often associated with a mix of blue and green pigments, and they can sometimes appear to change color under different lighting conditions.
