Abstract

Method for distinguishing colors, consisting either of basic colors with only a percentage share of basic colors greater than a predetermined threshold value, or of mixed colors with several percentages of participation of basic colors greater than a predetermined threshold value, in which the colors are first segregated by optical-electrical exploration in predetermined participation percentages of the basic colors and then analog electrical signals of said participation percentages of basic colors are obtained, which are transformed by amplitude discrimination into digital signals and then they are logically evaluated, characterized in that for the evaluation, in addition to the signals corresponding to the participation percentages of basic colors, also signals derived by division or addition and/or subtraction of the analog signals from the participation percentages are used of the basic colors, and why these derived signals are combined in such a way with the signals corresponding to the participation percentages of basic colors that between all the basic and mixed colors that you want to distinguish, separation zones are formed in which it is impossible any color distinction.
