An image processing method for generating a gradation image, including the steps of: (a) acquiring a coordinate of a start point, a color value of the start point, a coordinate of an end point, and a color value of the end point; (b) setting either the number of pixels between the start point and the end point that is calculated on the basis of the coordinates that are acquired in the coordinate-and-color-value acquisition (a) or the number of colors between the start point and the end point, whichever is smaller, as the number of complementary colors of a complementary color list; (c) creating the complementary color list that has the number of complementary colors that is set in the complementary-color-number setting (b); and (d) generating the gradation image with the use of the complementary color list that is created in the complementary-color-list creation (c).
