Abstract

If a set of colorants is to be used in making large numbers of specified colors, a calibration of the relationship between colorant composition and colorimetric specifications provides a very efficient means of procedure. In the case discussed, samples exemplifying the Munsell renotation were painted from such a calibration. A set of six chromatic paints plus black and white was first chosen on the basis of color gamut, fastness, and other physical properties. Since mixtures of two chromatic paints plus black and white provide three degrees of freedom, such mixtures are sufficient to obtain any color within the gamut of the chosen paints. The required calibration, therefore, must relate the ratios of chromatic paints, black, and white to colorimetric specifications within the gamut. This calibration was made by painting samples of a constant ratio type colorant mixture system, determining the CIE and Munsell specifications, then establishing graphs of the relation between colorant ratios and color coordinates. The mixture formulas for the desired Munsell renotation samples were then read from these graphs.
