Ahmes-Nefertari, Amenotep l's mother, was the first to enjoy an official cult after her death because of her eminent priestly functions, and this was of course fervently continued during succeeding dynasties. Having been deified, she appears in many monuments as a black-skinned queen -a rare privilege, previously granted only to gods or deified kings. The black colour that then differentiates her from other persons of her rank seems in the event to denote sanctification : her new physical appearance was thus a tangible sign that she had arrived in the world of the divine. It was no doubt on the basis of a similar principle that the queens of the Ramesside era, in having themselves depicted in their tombs with pink skin, also wished to indicate that they were diffe- rent in nature from other women (cf view 17 from the craftman Inerkhau's tomb) Top of Page
She may have been depicted as being black-skinned, but Egyptians took great liberties with skin color in tomb paintings. Osiris was always green; royal ladies almost always yellow; later Queens of the 19th and later dynasties sometimes portrayed with pink skin; men whether royal or not always portrayed as brown-skinned....just traditional representations.
