Abstract

A transition from one mixed color to another, the target color locus (Z) in a color system such as e.g. the standard chromaticity diagram (CT), is effected along a stored path (pi) from a succession of color loci which avoids undesired color mixing regions. A change between target color loci (Z) is effected from an instantaneously attained color locus (A0) by transition to an adjacent color locus in that path of the stored paths (pi) which leads as closely as possible past the instantaneous color locus (A0) and which then avoids undesired color mixing regions on the way to the notified target color locus (Z).
