While some people may appear to have irises that are black, they don't technically exist. People with black-colored eyes instead have very dark brown eyes that are almost indistinguishable from the pupil.

What is the darkest eye color?

Brown eyes are the darkest and also the most common. Green is the least common colour, with one exception. That exception is red eyes, which only people with a medical condition known as albinism have.

Are eyes brown or black?

When an object absorbs light, it looks dark. But when it doesn't absorb light, the light is reflected and the object is the color of the light it reflects. Light reflected from your eye is from the blue part of the color spectrum. Brown eyes have a lot of melanin, so they absorb light, which makes them dark.
