A quantum scheme developed for 'color coding' a set of objects to record which one is which was analyzed. In this quantum case, only N/e distinct 'colors' were required as compared the classical case where N distinct colors were required to color code N objects. It was observed that the objects may still be correctly distinguished with some success probability less than 1, if the number of colors is less than optimal. The results show that the success probability of the quantum states scheme is better than the classical scheme and is information-theoretically optimal.
