North africans are as black as the rest of africa.The Moors would be black in the U.S., the Egyptians of the Egyptian countyside(original Egyptians) would be black in the U.S., the Sudanese would be black in the U.S. When the Arabs invaded Africa, after the time of the Prophet(pbuh). The Qur'an didnt out law slavery, it regulated slavery and humanized it. The Arabs intermarried with their slaves(Arab father and African mother the child is Arab). Some Africans accepted the Arab culture without intermarriage(They consider themselves Arabs, Nubians).So in Norht Africa the Western term of race doesn't apply, because your'e black(african) if you don't speak arabic or accept their culture(muslim or non-muslim). The majority of arabs would be considered Black in the U.S.(one drop of Black blood).
Assalam alaykum!
