Color converting apparatus and color converting method for designated-color printing, and computer readable recording medium

A method of converting color for designated-color printing, comprising:

• a color-space converting step of converting a designated-color designated by a printing command to a converted-color in a color space represented by brightness, saturation and hue of color;
• a color classifying step of classifying the converted-color to one of plural classified-colors on the basis of the brightness, saturation and hue of said converted-color;
• and
• a classified-color/printing-color correlating step of selecting one printing color correlated with the one classified-color from among one or more printing colors, based on color correlating-relationship information, wherein the color correlating-relationship information sets correlating relationship between the plural classified-colors and one or more printing colors, and of correlating the selected printing color with said printing command.

A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a computer to perform the following steps:

• a color-space converting step of converting a designated-color designated by a printing command to a converted-color in a color space represented by brightness, saturation and hue of color;
• a color classifying step of classifying the converted-color to one of plural classified-colors on the basis of the brightness, saturation and hue of said converted-color;
• and
• a classified-color/printing-color correlating step of selecting one printing color correlated with the one classified-color from among one or more printing colors, based on color correlating-relationship information, wherein the color correlating-relationship information sets correlating relationship between the plural classified-colors and one or more printing colors, and of correlating the selected printing color with said printing command.
