1. A method performed at least in part by a computer, the method comprising applying a selective tristimulous correction to device-independent coordinates using a piecewise linear correction function, wherein the piecewise linear correction function is defined such that a maximum of the piecewise linear correction function occurs at a boundary condition of a corresponding device-dependent color space and the piecewise linear correction function is linearly reduced to zero or approximately zero as values in the corresponding device-dependent color space approach either a different boundary condition or a neutral axis.
