Abstract:
1. A computer-implemented color processing method for adjusting colors of a specific region, which is a subject of the adjustment in a color image, the color processing method comprising: calculating a color adjustment distance, which is an Euclidean distance in a color space between a representative color defined in the color space representing the specific region in the color image and a target color, which is target of the adjustment and also defined in the color space, using a computer on the basis of the representative color and the target color; and deciding, using the computer, a reproduction color in the color space expressing the representative color of the specific region after the adjustment on the basis of the color adjustment distance, the reproduction color being located in the color space between the representative color and the target color, and the reproduction color having a reproduction distance, which is a distance between the representative color and the reproduction color, wherein the reproduction distance increases with increase in the color adjustment distance when the color adjustment distance is smaller than a certain value and decreases with increase in the color adjustment distance when the color adjustment distance is larger than the certain value.
