Differences in color change due to bronze colors and the optical interference state related to bronzing are suppressed among multiple print modes. The blue primary color “Blue” in the standard RGB gamut is mapped to a point (color) that has moved in the clockwise direction, and that color is taken to be the primary color “Blue-s” in the Standard mode gamut. As a result, when an observer observes this color, the color shifted in the counter-clockwise direction is perceived as a color of the same hue as the primary color “Blue-f” in the Fine mode gamut, suppressing the difference in perceived color between the Fine mode and the Standard mode.
