Claim:
1. A method of gamut mapping comprising: generating, by one or more processors based on a first plurality of color values and a second plurality of color values, a first second-order or higher response-surface regression model that maps color values corresponding to the second color space to color values corresponding to the first color space, wherein the first plurality of color values correspond to a first color space and the second plurality of color values correspond to a second color space; receiving, by the one or more processors, a third plurality of color values, wherein the third plurality of color values correspond to the first color space; receiving, by the one or more processors, one or more measured color values corresponding to one or more colors displayed by a first target display, wherein the one or more measured color values correspond to the second color space, and wherein the third plurality of color values are associated with the one or more measured color values; generating, by the one or more processors, a predicted color value for each of the one or more measured color values by inputting each of the one or more measured color values into the first second-order or higher response-surface regression model, wherein each predicted color value corresponds to the first color space; and generating, by the one or more processors based on the one or more predicted color values and the third plurality of color values, a second second-order or higher response-surface regression model that maps predicted color values output by the first second-order or higher response-surface regression model corresponding to the first color space to color values corresponding to the first color space.
