Effects of Yellow Illumination on Color Confusion
This study used Farnsworth-Munsell 100 Hue Test System (FM100) to investigate how yellow lighting and white lighting affect color confusion as compared to sunlight. Forty college students with normal color vision were recruited as subjects. The experimental setup involved lighting that is incidenting from the ceiling at 90°angle on the FM100 with an illuminance of 550 lx; the subject is viewing the FM100 at a 45° angle. When all of the color chips of FM100 are fully discriminable (under sunlight), they can be arranged in a color circle (FM100 color circle) with equal hue steps similar to that of a 100 Munsell hue circle; however, under colored lighting, colors may be confused so that some of the color chips may be misplaced. Color confusion is measured by counting up the number of times a color chip is misplaced, which is called error score. All error scores are plotted on the FM100 color circle, which is called the color error sheet, to reveal the range and severity of color confusion due to that colored lighting. The results indicate that the yellow lighting significantly introduces color confusion, but the white lighting does not; the yellow lighting does not cause serious confusion in the yellow (its own color) and blue colors (complementary of yellow), but causes significant confusion in the green and red colors. On the error scoring sheet, both the two non-confusion series and the two confusion series are complementary and orthogonal. This observation leads us to form the hypothesis that colored lighting does not cause significant color confusion in its own complementary colors, but it does on its orthogonal colors.
