Abstract
A system and method are provided for producing a color palette including a multitude of color patterns for a predetermined coloring process with a multitude of defined base colors and for a predetermined substrate. The individual color patterns are systematically, especially equidistantly, defined in a mathematically defined color space by the way of color coordinates describing the color space. The spectrum of the color pattern is synthesized by calculation for each color pattern in the color space by way of a color mixing model representing the predetermined coloring process and the predetermined substrate, whereby that spectrum is selected having the highest color constancy. The spectra synthesized by calculation are stored in relation to the color coordinates of the underlying color patterns. Through use of a mathematical/physical basis (such as the CIE-system), it is possible to define a visually equidistant color space and assign a spectral curve to individual points having the best color constancy.
