A color chart has been developed to facilitate quantitative or visual evaluations of color reproduction processes employed in photography, television, and printing. The 4x6 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.
