Well thankfully the God I worship states in His books via his messenger that he created all of mankind to not be superior over another except by good deeds and piety.
Our Prophet stated: "An Arab is no better than a non-Arab. In return, a non-Arab is no better than an Arab. A red raced man is no better than a black one except in piety. Mankind are all Adam's children and
Adam was created out of clay" [Al-Bukhari and Muslim, on the authority of Abu Musa].
Many of my friends are married to men of different races and nationalities and each of them have very blessed good marriages. My own hubby is of dutch origin, hence white skinned, and Al Hamdullilah our marriage is doing just fine.
And on a side note kids from white and black parents have gorgeous complexions, Masha Allah, hence the combo of ebony and ivory rocks!
