Relations of the glossiness and lightness incorporated into the automatic glossiness and color differences discrimination system

The relations of the hue, chroma and lightness in the achromatic and chromatic colors had been investigated. And the automatic glossiness and color differences´ discrimination system has been developed. This time has circumstantially investigated to the relations of the glossiness and lightness in the achromatic and chromatic colors. As a result, it was understood that the combination ratio with RGB in a chromatic color was due to the variation of the glossiness. In an achromatic color, it was understood that the variation of RGB values was due to the variation of the lightness values from black to white. Moreover, the output voltages for the intensity of reflected light to the glossiness of the chromatic color has increased on the linear function. The white of an achromatic color has located on an upper side of the chromatic color, and the black of an achromatic color has located on a lower side of the chromatic color
