ABSTRACT:
Kits which allow colors to be identified and thereby communicated by their unique chromatic and/or achromatic characteristics include a number of discrete color plaques. These color plaques are preferably arranged in chromatic and achromatic series such that individual plaques may be combined with other plaques to form a stack so that the collective color characteristics of the stack may be observed visually. In preferred embodiments, the chromatic plaques in the kits will be arranged in rows and columns in order of the individual plaque's color hue and value characteristics. The achromatic plaques, on the other hand, are simularly arranged in columns and/or rows in order of the plaque's particular achromatic value characteristic. Since the kits of this invention have the unique capability of allowing chromatic and achromatic plaques to be combined in any selected manner, virtually any color in the spectrum can be matched in any level of hue, chroma and/or value in addition to its particular level of transparency, translucency or opacity.
