Can Africans have blue eyes?

The color of our eyes comes from the appearance of the pigment that is present in the iris, the central part of the eye.
What causes Greeneye?
Green eyes are a genetic mutation that produces low levels of melanin, but more than blue eyes. Instead, because of the lack of melanin in the iris, more light scatters out, which make the eyes appear green. Changes in light make lighter eyes look like they are changing colors like a chameleon.

Although hazel mostly consists of brown and green, the dominant color in the eye can either be brown/gold or green.
Why do some mixed race people have blue eyes?

Yes. Not only can blue eyes skip a generation, they can skip multiple generations. If blue eyes are already in the family, there is no guarantee that a parent will pass them on to their child. Blue-eyed parents can give birth to brown or hazel eyed offspring, with the blue eye mutation lying dormant within the child’s genetic make-up.
