ABSTRACT:
A color value classification system employing a combination of four basic colors and five hues substantially covering the visible spectrum. The specific hues and tints are not equally spaced from the standpoint of wavelength, but are positioned within the visible spectrums to facilitate the making of other hues, increasing or decreasing contrasts, other shades and similar variants. The provision of twenty basic hues and percent tints permits the reproduction of the colors in commercially usable forms including printing inks, transparent color sheets, colored papers, coating materials and paints. Using a relatively small number of color variants, the teaching of color is materially simplified, as in the establishment of simple translation of art copy into forms for convenient replication.
