Analysis of Appearance of Color under Mesopic Vision Corresponding to Illuminance Levels Using Color Recognition Characteristic Model Based on Opponent Color Response Function

Abstract

In order to study the appearance of colors under mesopic vision in response to changes in the spectral distribution of light sources, we have validated our previously proposed model of color recognition characteristics based on the opponent color response function. First, we developed a wavelength tunable light that provides light sources with various spectral distributions. Next, we generated four white light sources with different spectral distributions using this tunable light and conducted an experiment to evaluate the change in color appearance under mesopic vision. Finally, the experimental results were compared with predictions made using the color recognition characteristic model based on the opponent color response. The predictions were in close agreement with the experimental results, indicating the effectiveness of the model.
