In this paper, we propose a numerical representation method of color by using a color image processor. We develop an HSV chart to show the color characteristics graphically from the relative frequency and relative cumulative distribution of HSV parameters, which have been applied widely in the field of computer graphics. The difference of color among scenes is shown by the Euclidian distance calculated from the parameters of the HSV chart. It is made clear from the analyses of some factory models that the HSV parameters of beautiful color are quite different from those of notice-able color.
