ABSTRACT:
Room light, especially fluorescent lighting is corrected to provide a green-magenta balance comparable to that of natural sunlight by measuring the green-magenta balance of the lighting within the room and applying a filter to each light source to bring the balance to the desired level. This ameliorates the detrimental physiological effects of an unnatural light spectrum in a workspace.
