PROBLEM TO BE SOLVED: To provide an inside/outside determination program capable of improving the precision of inside/outside determination as compared with that using conventional programs. SOLUTION: The inside/outside determination program is a program for determining whether a determination target color belongs to a color reproduction range of a printer outputting colors on the basis of color data of an RGB color space or not on the basis of data of the color reproduction range and makes a computer execute: a polyhedron extraction step of extracting a polyhedron in a CIE-LAB color space from the data of the color reproduction range; a center point calculation step of calculating a center point 72 of a segment 71 connecting a white point 65 corresponding to white of color data and a black point 66 corresponding to black of color data in the polyhedron; and an inside/outside determination step of determining that the determination target color belongs to the color reproduction range in the case that a segment 92 connecting a determination target color point 91 and the center point 72 does not cross the polyhedron in the CIE-LAB color space.
