Examinations of Color Emotions for Average Faces

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 pertain to face colors by using of a light system controlling color rendering property. The system we developed in the previous study has four color (red, green, blue, and yellow) LEDs to enrich color rendering property. This study provides a comprehensive discussion of color rendering properties and color preference to average face by summarizing past two studies. The first study examined color emotions against skin color under various color rendering properties. 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. The second study assessed relationships between color emotions against averaged face irradiated by various illuminants with different color rendering properties. As a result, we confirmed that the color rendering property certainly affects color preference, and we obtained regression models to represent color emotions by color rendering properties. Based on the model of the relationship between color emotions and color rendering properties obtained through these two studies, a comparison of skin color itself and color emotions as a face color is discussed. Specifically, the results suggest that color shifts in the red and green directions have different effects on the impressions of single colors and average faces.
