The secret of good paint matching (fabrics and paper is to get a match under widely varying light conditions. This is only possible if the spectrum of reflected light is wide band (not narrow band peaks) so that the eye's analysis gets an input from all wavelengths and then it can some with more varied illuminants. A peak in one narrow range of wavelengths can miss some of the wavelength bands that you can get with CFLs and that will give lunatic results.Yes, lighting. Back in the 60's I was at a party where different parts of the room were illuminated with different colours of lights. My girlfriend had red eyes under a green light and green eyes under a red light. Complicated, indeed!
Those CFLs were a temporary blip in the history of colourimetry and we are well rid of them, imo.
