1. A method comprising:
receiving, by a computing device, information for estimations of color saturation variations of different hues in a working color space with one or more properties of estimated responses of a human vision system (HVS) to color stimulus; and
generating, by the computing device, one or more color saturation variation models based on the estimated responses of the HVS to color stimulus.
