The ISCC-NBS method of designating colors was published in the Journal of Research of the National Bureau of Standards 23, 355 (1939) RP1239. The Inter-Society Color Council approved the refinement of this method and encouraged the Bureau to compile the dictionary; most of the data upon which the translation of the individual color names into ISCC-NBS equivalents is based were supplied by its individual members who also helped to check the voluminous tables. The particular contributions of these and other individuals are acknowledged at appropriate places in the text. The Bureau is glad indeed of this opportunity to point out the cooperative nature of this project.
