Literally some of the first American anthropology studies were on the differences in visual color perception between Americans and Inuits caused by culture, back in the 1910's, by a guy whose original academic study and training was in the physics of light and color. It's literally one of the oldest studies of anthropology and what kicked off the field, the fact that vision scientists haven't accounted for it and this is news to them is a damning indictment of the lack of interdisciplinary work.
