This study focuses on the condition of light color, which is one of the requirements that make up the comfort of sunlight filtering through foliage, and aims to reproduce it as artificial lighting. With this purpose, we conducted four subjective evaluation experiments in experimental room as office or relaxation room. Subjects evaluated the room’s lighting environment which was composed of type of green filter, size of luminaire, ratio of green and white light and illuminance level on the desk. As a result, we found most preferred combination of those factors as well as the positive response ratio of each condition.
