Abstract

Emotional responses to color stimuli are referred to as color emotions, and relationships between color attributes and them have been discussed in past studies. In the current study, we reveal relationships between color rendering properties and color emotions to provide a light system controlling color emotions along with color rendering property.We developed such a system and conducted two evaluations of the system performance and color emotions under the light generated by the system. The system we developed in the current study has four color (red, green, blue, and yellow) LEDs to enrich color rendering property. In addition, we conducted a subjective assessment to explore relationships between color emotions and color rendering properties. In the assessment, we studied color emotions against facial skin irradiated by various illuminants with different color rendering properties. We prepared sixteen different light conditions and the participants of the study were asked to respond to the stimuli with fifteen Likert scales. As a result, we confirmed that the color rendering property certainly affects color emotions, and we obtained regression models to represent color emotions by color rendering properties. Furthermore, we found that male and female test subjects experience different color emotions based on skin color.
