It is also commonly expected to provide an additional subjective benefit by making Display work pleasant. However, inappropriate use of color can result in poor performance and higher incidence of visual discomfort. In this study, we used reaction speed and subject preference rating as indices for accessing the effects of color and luminance. For accurate and eThe results showed that (1) Stimulus color significantly affected visual performance. (2) Stimulus luminanceand stimulus color significantly affected subjective preference. (3) Response surface of reaction speed and subjective preference were constructed, correlation analysis showed that these two prediction model were better thanLippert''s DE and CIE1976 DE.
