Abstract: The color deviation occurs when LED lighting on objects of different color. This study mainly investigated the effects of the elements of color (brightness, saturation and hue) on color deviation during LED lighting. Users were invited to distinguish the comparison color samples consisted of three variables (brightness, saturation and hue). Results revealed that the effects of elements of color on color deviation of LED light were significant. Additionally, the color deviation of LED light were different involving different principal hues (cyan, magenta, yellow). For cyan, the effects of brightness on saturation deviation and hue were significant, while on brightness and hue were significant for magenta. The deviation of brightness, saturation and hue under cyan as well as saturation under yellow were significantly affected by saturation. Hue significantly affected the deviation of hue both for cyan and yellow as well as the deviation of saturation for magenta. These results have implications for lighting design in shopping mall and other public space.
