Abstract

Current American practice in color measurement is reviewed from the standpoint of instrumentation practice, measurement concepts, and computational methods. Instrumentation practice is described for spectrophotometers, abridged spectrophotometers, and tristimulus colorimeters. Measurement variables discussed include photometric and wavelength scales, standards and standardization, illuminating and viewing geometry, and instrument sources simulating standard illuminants. Computation methods practiced for obtaining color coordinates and color differences are discussed. Topics indirectly related to the measurement step, such as the basis of colorimetry, color mixing laws, and computer color matching, are specifically excluded from this paper.
