I once worked with someone who did not see colour at all. Not an archaeologists but a scientist. He had no problems as he perceived the world in subtle tones (shades of grey) It was interesting talking to him as he fully understood the physics of colour but as a personal experience it meant nothing to him. Had no problem with traffic lights cause of the position of the lights. Know several people who are red green colour blind, you can usually tell cause of the none too subtle clothes combinations. Had to tell one that what he saw as a complimentary combination of browns was a total clash of red trousers and green jacket.
