ABSTRACT:
A method for generating the characteristics of a set of colors involves selecting at least two, and typically more reference colors. Each of the selected reference colors is described by a set of color characteristic data indicating the reflectance of each color at each of a set of predetermined wavelengths; and descriptions of the intermediate color samples are generated by computer the relative proportions of each base color which characterizes each intermediate color and calculating a reflectance value at each wavelength for the color to be generated proportionate to the reflectance values for each base color at the corresponding wavelength. A set of color samples is created as a result of the method for generating the characteristics of the colors and arranged in a geometry indicative of the method. A system for generating the color samples data has storage for storing the photometric characteristics and other data; a central processor under software control for accessing the stored data, computing the relative proportion of each reference color comprising each color to be generated, and computing the reflectances at each wavelength for which color reflectance data is stored for each intermediate color; and an output for outputting the data generated by the central processor.
