1. A method of gamut mapping comprising: receiving, by one or more processors, a first plurality of color values, wherein the first plurality of color values correspond to a first color space; receiving, by the one or more processors, a plurality of measured color values corresponding to a plurality of colors displayed by a first target display, wherein the plurality of measured color values correspond to a second color space, and wherein the first plurality of color values are associated with the plurality of measured color values; generating, by the one or more processors, a second plurality of color values from the plurality of measured color values using a color specification that maps color values corresponding to the second color space to color values corresponding to the first color space, wherein the second plurality of color values correspond to the first color space; and generating, by the one or more processors based on the first plurality of color values and the second plurality of color values, a second-order or higher response-surface regression model that maps the first plurality of color values corresponding to the first color space to the second plurality of color values corresponding to the first color space.
