Abstract
In an example, a method of gamut mapping may include generating 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. The method may include generating predicted color values for measured color values by inputting measured color values into the first second-order or higher response-surface regression model. The method may include generating, based on predicted color values and a 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.
