Abstract
This research aims at identifying the differences of color perception by applying 6 types of LED lighting on 4 types of leather finishing. The 6 lighting types include three levels of correlated color temperature (CCT) multiplied by two illuminance levels. The 4 types of leather finishing include red and brown, with grains and without grains. The dependent variables were blackness, saturation and hue of 3 characteristics encoded for each color in the Natural Color System. A total of 15 volunteers participated the experimental study. The results reveal that CCT, illumination and color have significant effects on the perception of color differences. At the same time, a three-factor interactive effect of grains, CCT and color, also shows significant effects. The results of this study can provide references for the display lighting design of leather products and the color design of leather products under different lighting conditions.
