A reproduction color storing section stores pieces of color information in association with a color range that is stored in a color range storing section and includes a fluorescent color targeted for detention. Each piece of color information specifies a reproduction color candidate usable for reproducing the fluorescent color. The pixel extracting section extracts, from image data, a pixel having the fluorescent color based on the color range. A display control section reads, from the reproduction color storing section, the pieces of color information corresponding to the fluorescent color of the extracted pixel and displays the reproduction color candidates specified by the pieces of color information on a display section. The reproduction color receiving section receives a reproduction color selected by a user from the displayed reproduction color candidates. The fluorescent color reproducing section replaces color information of the extracted pixel with color information specifying the received reproduction color.
