Abstract
A color processing apparatus includes an input range obtaining unit configured to obtain an input range of input color data represented by a first color space that is an extended color space, a setting unit configured to set grid point coordinate values for each of a plurality of color components included in the input color data, and a generating unit configured to generate a look-up table by performing conversion processing on each of look-up-table coordinate values corresponding to grid point coordinate values set for the plurality of color components, and storing a result of the conversion processing in the look-up table. The setting unit sets the grid point coordinate values such that each of the primary colors in a second color space that is a base color space is located at a grid point and the color components have the identical grid point coordinate values among the primary colors.
