The light skinned Egyptians of today are not descendants of the ancient Africans or Nubians. Rather the light tones are as a result of the later invasions by and intermarriages with Arabs and other groups.
Reflections:
Understand that complexion is NOT linked to intellect and beauty, both are diverse and there is no single ideal.
