Abstract
A computer-implemented method for generating a color map using a color space, the generating including selecting lightness points representing lightness values, generating a lightness plot based on the lightness points, the lightness plot non-linearly increasing from a minimum lightness value to a maximum lightness value, and selecting chromaticity points, where the chromaticity points are represented using a plurality of dimensions, and the chromaticity points representing chromaticity values. The method includes generating a chromaticity plot based on the chromaticity points, and associating chromaticity values along the chromaticity plot with respective lightness values along the lightness plot, the associating specifying a plurality of colors. The method also includes identifying an in-gamut range for an RGB representation of the plurality of colors, the RGB representation provided in an RGB color space, and converting the color map from the color space to the RGB color space.
