The tertiary color names used in the descriptions of RGB (or equivalently CMYK) systems are shown below. The primary colors in an RYB color wheel
Color printing series of steps, or transformations, to generate a quality color reproduction. The following sections focus on the steps used when reproducing a color image in CMYK printing, along with some historical perspective. Woodblock printing on textiles preceded printing on paper in both East Asia and Europe, and the use of different blocks to produce patterns in color was common. The earliest way of adding color to items printed on paper was by hand-coloring, and this was widely used for printed images in both Europe and East Asia. Chinese woodcuts have this from at least the 13th century, and European ones
