>>13427490Haa yes, that guy.
That's the second version of the pre-dinastic god Hapi which was blue, second version is Min which was sometimes blue but most often black and a few times light skinned, later there is amun-min which is more often colored in the typical clay color.
Anyway many gods are color coded in Egyptian depiction some green, some blue, some black, some white for answering your first question.
If you actually want to have a good answer on the race of the ancient Egyptians a black geneticist run DNA testing on several hundred mummies just for that.
Found that % of black DNA was around 2% to 3% on average and the older the mummy the less black DNA was present. However he also confirmed that 2 late dynasties (13th and 18th if i remember correctly) had much black DNA as they intermarried with Nubian royalty. However both dynasties ruled only from Thebes (near Nubia) and were quite short lived as they ruled during a time that Egypt split into 2, the marriage make sense as it would have been impossible for higher Egypt (southern Egypt) to fight the opponent of the much more populated Cairo if the Nubians invaded from the rear.
So a few half kangz actually existed. Nonetheless ancient Egyptians were not Nubians, nor any sub Saharan phenotype.
About the study anyway the reason for a considerable increase in black DNA in modern Egypt compared to ancient Egypt is manly due to the Arab slave trade during the ottoman empire that brought in millions of black females much later on (also males but due to the ottomans practicing male castration they did not count towards the current genetic makeup of Egypt).
