Abstract
In an example, a method of calibrating a white point of a display may include receiving a plurality of color values, and one or more measured color values corresponding to one or more colors displayed by a first target display. The method may include generating, based on the plurality of color values and the one or more measured color values, a second-order or higher response-surface regression model that maps color values corresponding to a second color space to color values corresponding to a first color space. The method may include generating predicted color values for a specified white point by inputting a plurality of specified color values corresponding to the specified white point into the second-order or higher response-surface regression model, where each predicted color value may correspond to the first color space and each of the specified color values may correspond to the second color space.
