FIELD: physics.
SUBSTANCE: in the method, colour difference is defined by the length of the path, expressed in chromatic thresholds, between colour points in non-uniform contrast space, wherein the chromatic threshold in at least one point on that path is considered. The corresponding apparatus and machine-readable medium are also provided.
EFFECT: method enables to determine the length of the shortest path in chromatic thresholds between colour points in colour space.
