Abstract: In this paper, the effects of absolute color discrimination were comparedunder eight different lightings, i. e. four white lightings and four color edlightings. The level of luminance is 3 nit. The results indicated that the effectsof absolute color discrimination of white lighting are better. than that of colo-redl ightings. Under the condition of red lighting, color discrimination is worsethan that under other colored lightings. The results also indicated that the effects of discrimination of 11 colorsused in this experiment were different. It is easy to discriminate colors of redand orange from other colors, and difficult to discriminate colors betweenyellow and white, green and light blue, deep blue and black, because theyare easily confused.
