Heursistics for programming real-time color recognition hardware, controlled by a symbolic (Prolog) processor, are described. The paper addresses the engineering aspects of color recognition and its application to such tasks as industrial inspection and sorting. The techniques discussed are heuristic, not algorithmic; they are not particularly well suited to those applications where there are subtle color changes. However, in numerous experiments, they have been found to produce useful results, in a wide range of important industrial inspection and sorting tasks, where relatively coarse color discrimination is sufficient. The application of these techniques to the inspection of standard multi-color packaging materials is highlighted.
