Abstract
A method includes receiving information specifying a color gamut. The color gamut corresponds to a range of colors producible by an output device. The method further includes receiving a first indication of a first color associated with a first point in a geometrical representation of the color gamut in a three-dimensional (3D) color space. The method further includes generating, based on the first color, a second indication of a second color that is included in the color gamut. The second color is associated with a second point in the 3D color space. The second point is identified based on a particular value of data associated with a plurality of distances between the first point and a subset of points of the geometrical representation. The subset of points includes more than one and fewer than all points of the geometrical representation.
