1. A method comprising: defining a bounded space approximating a color gamut based on at least a first plane approximately tangential to the color gamut; identifying an input point, wherein the input point represents a color that is outside the bounded space; determining, by operation of a computer, a first distance between the first plane and the input point, the first distance being measured in a direction normal to the first plane; determining, by operation of a computer, a second distance between the input point and an aim point, the second distance being measured in a direction normal to the first plane, wherein the aim point represents a color within the bounded space; and determining, by operation of a computer, 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.
