We present a hybrid color mapping (HCM) designed to preserve a selected region in chromaticity space while exploiting the larger gamut of the intended target display. Our method is based on the hypothesis that outside a certain set of critical colors, people are less particular and prefer a more saturated appearance if available. This hypothesis was borne out in the subject study we conducted. While other practitioners have implemented similar gamut-mapping techniques, our definition of preserved colors is more flexible and not based purely on saturation level. We employ an exponent or "acceleration factor" in our mapping to better preserve neighboring colors for a more natural appearance. Our method further avoids contrast and luminance changes, works between arbitrary gamuts, and is a fully invertible one-to-one mapping between color volumes.
