Abstract

One embodiment provides a method comprising determining a target color gamut of a display device, an inner zone of the target color gamut, and an outer zone of the target color gamut. The method further comprises dynamically determining, based on the inner zone and the outer zone, a path along which an input color in a source color gamut of an input content moves. The input color is outside the inner zone. The method further comprises mapping the input color from the source color gamut to an output color in the outer zone based on the path. The input color is rendered as the output color during presentation of the input content on the display device.
