To permit color reproduction of signals representing a color image by burning off a metalized layer (2) on an insulating substrate (1, 3), by contacting the metalized layer with an electrode (35) and passing a current pulse through the electrode, the color pattern is placed beneath the metalized layer and comprises groups (17) of colored dots which are essentially hexagonal in shape and positioned closely adjacent each other to form a color dot pattern of beehive appearance. One of the color dot pattern preferably additionally has a characteristic other than color to distinguish it from the others and provide a locating marker; the additional characteristic may, for example, be magnetic particles on the dots to be sensed by an electromagnetic transducer, similar to a tape recorder head, or a difference in reflectivity which can be sensed by an optical transducer.
