While ancient Egyptians were, by all accounts, black, the fact remains that their civilization was under foreign rule for the last 340 years before its collapse. There are literally numerous funerary coffins from that time period—different from a traditional Egyptian sarcophagus—that bore portraits depicting the person inside. These are referred to as Fayum mummy portraits. They are clearly a departure from Egyptian practices and artwork, and are considered as direct Roman influence, so yes: There is quite a lot of evidence as to the Greek and Roman occupation of Egypt.
