A method includes defining a bounded space approximating a color gamut based on a plane approximately tangential to the color gamut. The method further includes identifying an input point and determining a first distance between the plane and the input point. The first distance is measured in a direction normal to the plane. The method also includes determining a second distance between the input point and an aim point. The second distance is measured in a direction normal to the first plane. The method further includes determining a clipped point based on a ratio between the first distance and the second distance, the clipped point representing an approximation of a color on a boundary of the color gamut.
