COLOR-RENDITION CHART.

Abstract

A color chart has been developed to facilitate quantitative or visual evaluations of color reproduction processes employed in photography, television, and printing. The 4 multiplied by 6 array of patches, each 50 mm (2 in. ) square, includes spectral simulations of light and dark human skin, foliage, blue sky, and a blue flower (chicory). Additive and subtractive primaries and a six-step neutral scale are included for analytical studies and other colors fill a wide gamut. Each patch is characterized by spectral reflectance factor; assigned name; CIE (1931) x, y, and Y; Munsell notation; and ISCC-NBS name.
