The phenomena that is such eyes is rare amongst us. But there has been a case or two that dragged controversy amongst our society couple of times. But for us, it's when one has coloured eyes... long ago it was affiliated with taboos and bad luck.
Then it became a thing as the effects of interracial relationships and marriages. Everyone wanted a child with a set of coloured eyes. But it was always interesting when the parents are both African and their child had coloured eyes. Today, we understand it happens when our iris doesn't have melanin.
I can see why it would be unusual and really beautiful if both parents, being African, to have a child with colored eyes. I’m glad it is not longer considered bad luck and there is a reason for it happening.
