Abstract
Abstract A method for converting color coordinate values of a target color from a first three-dimensional color space to a second three-dimensional color space, includes looking up the target color in a look-up table and interpolating each color component of the target color only in a single dimension between adjacent grid points in the look-up table. Preferably, each color component value shares a common grid point upon which interpolation is based for all color component values, with the common grid point lying on the neutral gray axis when a cube enclosing the target color includes the neutral gray axis of the first three-dimensional color space.
