Pick a skin color, any skin color, and you will find it native in Egypt.
I've been there twice and was rather amazed at what was "an Egyptian".
Geography -- East of Libya and North of Sudan-- and history, are what have most affected their genetic make up.
In the North in places like Alexandria, you'll find a lot of people who could pass for Europeans. In the Central part, they look like Arabs and in the South, Nubian Black.
The historical issue was that when Alexander the Great conquered Egypt, the descendants of his right-hand man, Ptolemy, sat of the throne of Egypt. And in Pharoaic tradition, brother married sister, so theoretically their bloodlines should have been pure Macedonian Greek. (Cleopatra was the last of the Ptolemies.) But there have been some recent finds that could indicate that there might have been more to the dynastic genetic make-up than that.
In any case, these recent Eastern European finds are fascinating. Thanks for the heads up, rabs.
But look at Copts who are the closest to "undiluted" Egyptians
The Old and Middle Kingdom Egyptians were Afro-Asiatic peoples - see the picture above -- related to Semites and Berbers, so brown skinned.
Post the Middle Kingdom when they were conquered by the Semitic Hyksos, some mixing to lighter brown may have occured in the north and among elites
Then there were the conquests of Egypt by Libyans, by Assyrians, by Nubians, so some more admixture among the ruling classes
the Greek conquest and Roman seems to have been nearly exclusively among the ruling classes, leaving your street fellaheen the same genetically.
