Claim 9:
10. A non-transitory computer-readable storage medium storing a set of computer-readable instructions for controlling an image processing device, the image processing device includes: a display configured to display a printing target image; an input unit configured to input a specified color specified from among a plurality of image colors used in the printing target image displayed on the display; and a storage unit configured to store a conversion table mapping a plurality of input values to respective ones of a plurality of output values, the plurality of input values corresponding to respective ones of a plurality of grid points in a predetermined color space, the set of computer-readable instructions comprising:
a first display operation to display the printing target image on the display; and
in response to the input unit inputting the specified color in the printing target image displayed on the display in the first display operation, a second display operation to display at least one of a target color and a non-target color in a manner different from the at least one of the target color and the non-target color in the printing target image displayed by the first display operation,
wherein the target color is a color targeted for color calibration and is included in a color calibration space in the predetermined color space, and the non-target color is a color not targeted for the color calibration and is not included in the color calibration space, the color calibration space being defined by a predetermined number of first grid points and a plurality of second grid points,
wherein the first grid points are included in the plurality of grid points in the predetermined color space and define a first polyhedron, the first polyhedron being a polyhedron with a minimum volume enclosing the specified color and having the first grid points as vertices,
wherein the second grid points are included in the plurality of grid points in the predetermined color space and define a plurality of second polyhedra together with the first grid points, each of the second polyhedra being a polyhedron with the minimum volume having a predetermined number of specific grid points as vertices, the predetermined number of specific grid points being included in the first grid points and the second grid points and including at least one first grid point and at least one second grid point adjacent to one of the at least one first grid point, no grid point being positioned between each of the at least one second grid point and the one of the at least one first grid point, and
wherein the color calibration space is a space enclosed by the second grid points.
