Abstract: Tutorial stampers in logically related sets, such as 26 alphabet stampers, are fabricated with a different color associated with each member of the set. Both the marking fluid and at least a portion of the outer shell each marker match the color associated with the character imprinted by that marker. Preferably the marker cap matches the selected color and the character is imprinted on the marker barrel in the same color. For adults color is a re-enforcing visual cue to help quickly locate the desired character. For children the color difference helps fix in the child's mind the distinction of, for example, each letter of an alphabet or numeral of a number set. In the business world, different colors can be used, in association with a set of distinctive symbols to identify different functional portions of large organization and set of stampers organized in that way can be used, for example, in the organization's mail room to identify package destinations.
