Abstract
The method of generating color sample data includes the step of generating the color sample data for preparing a color sample of a color included in a difference area between a color gamut in an equipment independent color space which is expressed by a first color expression apparatus and a color gamut in the equipment independent color space which is expressed by a second color expression apparatus using an output profile which expresses the color and corresponds to one of the first color expression apparatus and the second color expression apparatus configured to express a color in at least a part of the difference area out of a first output profile representing a correspondence relationship between a coordinate value in an output color space depending on the first color expression apparatus and a coordinate value in the equipment independent color space, and a second output profile representing a correspondence relationship between a coordinate value in an output color space depending on the second color expression apparatus and a coordinate value in the equipment independent color space based on a coordinate value in the difference area.
