As soon as I saw Phillipe's delicate pastel image I immediately thought of Lucien Rudaux' map of lunar colors. The map appears in the 1967 volume, Larouse Encyclopedia of Astronomy and is also online; the earliest version I've seen is from 1928. Rudaux, like today's Bill Hartmann, was an astronomer as well as a talented artist. He apparently had extremely sensitive color vision for his map depicted hues that are remarkably consistent with modern color saturated images - see for example the details along the western edge of Mare Serenitatis. Radaux' most intense color is the Aristarchus Plateau, which even I once saw with a mustard hue. It must be some trick of the eye but I find that if I look closely at Rudaux's map and then switch quickly to the same area on Phillipe's image that the color momentarily seems more conspicuous.
