A variational model for spatially dependent gamut mapping is described that includes inputting a gamut constraint, choosing a one dimensional gamut projection scheme, including selecting a transform color coordinate system, computing transform equations, and verifying gamut conditions. The model also includes inputting an original image to be rendered, where the original image is in a given color coordinate system, transforming the gamut constraint, the image, and the transform equations to the transform color coordinate system, whereby a three dimensional function is transformed into a one dimensional quadratic functional, finding a minimum solution to the functional, and transforming a projected image in the transform color coordinate system into a color coordinate system of a rendering device.
