An attractiveness calculation unit calculates an attractiveness by using the color-scheme information. An importance degree storage unit holds importance degree information representing a relative degree of importance of each of the used colors and corresponding to information for which each of the used colors is used. A color-scheme appropriateness judgment unit calculates ordinal rank of the importance degree information associated with each of the used colors, calculates ordinal rank of the attractiveness associated with each of the used colors, and outputs a judgment result indicating whether or not the ordinal rank of the importance degree information associated with each of the used colors coincides with the ordinal rank of the attractiveness associated with the used color.
