Quantitative Evaluation of the Effect of the Spectral Distribution of an Illumination Source on the Appearance of Color under Mesopic Vision and Modeling of Color Recognition Characteristics

Abstract

We used a categorical ratio evaluation method to conduct experiments to evaluate the appearance of colors in mesopic vision under light sources with different spectral distributions. The experimental results showed that the appearance of color changed as the illuminance decreased. Also, the appearance of color was slightly different depending on the light source. Analysis of the results showed that transforming the opponent color response function can better explain the appearance of color in mesopic vision.
