ABSTRACT: The purpose of this study was to analyze the effect of chromatic lighting on the transition from the current emotional state to the desired emotional state. Most previous studies on color and emotion have analyzed the input-output relationship based on one-to-one correspondence between color and emotion under neutral emotion. In this study, we analyzed the relationship between the type of emotion and the lighting color and showed that the transition of emotion can change depending on the current emotional state even under the same lighting color. To improve the stability of experiments, the authors modified the emotion elicitation and analysis methods and compared the findings to our previous studies. We experimentally examined the effects of chromatic lighting on emotions induced by the International Affective Picture System (IAPS) using heart rate variability indices. The results suggest that there are chromatic illuminants that are effective in promoting or suppressing positive and negative emotions. In particular, the results of the heart rate data analysis were more stable and reliable for the chromatic illumination that was effective in promoting and suppressing negative emotions (investigated in the negative impression images) compared to the positive impression group.
