"We are the Fury"
Whether the variations are low compared to AAs is besides the point. The fact is that it is far from uncommon in African families. I have a friend of mine with twin sisters, where one is dark brown and the other is light brown with hazel-green eyes.
Less non-black variation is not besides the point as it implies lighter skin and more potential for phenotypic difference (mixed people differ more than pure race people when it comes to mixed features). Blacks actually don't have any gene for "green eyes", similar to East Asians, and if Africans are pure black, they shouldn't either (same as East Asians). Your family, while an interesting case, does not necessarily represent Africans. You're probably a outlier in this context. You could be ancestrally mixed like East Africans or a migratory Fulani or something which is besides the point.
In the Middle East, but I've lived in Africa as well.

If I didn't tell you I was from Africa you would assume that I was a typical AA.
Again you're an anecdote and your case does not prove anything. If you want to prove that Africans can have non-black variation like AAs, you' can post pictures of African tribal people so we can see their variation. Or else provide a study or something with proof of equal or similar skin tone variation.
