Central notations for the revised iscc-nbs color-name blocks

Abstract

Nickerso n and Newhall published, in 1941, the central notations of the original ISCC-NBS (Inter-Society Color Council-National Bureau of Standards) color-name blocks which were u sed in the preparat ion of the soil and rock color-name charts. In 1955, the ISCC-NBS color-nam e blocks were r evised to accord more closely with usage in the texti le and other fi eld s (NBS Circu lar 553). The central notations of these revised color-name blocks have been computed and are given in the prese nt paper in tabu lar form. A color chart s llow. ing t he central colors of the 267 ISCC-NBS color-n ame blocks wou1d se rv e for rapid determination of the J SCC-NBS color d esignation, es pecially in field wor k where spee d and ease of operation are more important than high accuracy.
