I have a theory based on the genetic of descendants and current inhabitants of West Africans....that when a West African and West African in the Diaspora has black elbows; that is from pigmentation, one which is not caused by trauma to the area. The women will possess LARGE BLACK AREOLAS which will mirror her elbows.
Ex.
-If she is dark skin like Meg Thee Stallion and she has black elbows, then her areolas will be darker or match the elbow color.
-If her elbow color covers a large radius of the elbow, then she will have bigger areolae in circumfrence around the nipple.
-If her elbow has pigmented dots, then she will have copious amounts of the Montgomery Vestibles that gradiates from the rich dark pigment of the areolae.
