I asked the artist, who has a lot of experiences with mixing colors (he has made several color palettes on conmission) and on lightning (he developed a combination of three types of lamps, which gives the best reproduction of daylight, consisting of a daylight LED lamp and two types of fluorescent lamps), and he said that he did not know of a rgb sensor that gives a faitfull reproduction of daylight colors. He said that to compare the quality one would have to compare it with the work in daylight condition. I do not know if this picture was taken with a multi-spectral camera or with a three (rgb) channel camera. Maybe with a multi-spectral camera one could find a method to accurately reproduce the experience of viewing the work in daylight conditions.
