To provide a method and a device for color processing to perform color reproduction adjustment easily and efficiently.

An initial color correction LUT is created, a variable for adjusting the initial color correction LUT is selected, and a plurality of color correction LUTs adjusted according to the variable are created with the initial color correction LUT as the center. From the plurality of color correction LUTs, a thumbnail image arrangement is printed and the most desirable image is selected from the printed thumbnail image arrangement. Taking a color correction LUT corresponding to the selected thumbnail image as an initial color correction LUT, the above-mentioned steps are repeated until a user's requirements are met, and a selected thumbnail image is printed in an appropriate size.
