Apparatus and methods are provided to map out-of-gamut points to in-gamut points. Embodiments transform image data for presentation on a display or medium having a gamut different from that of the image data. Different mapping algorithms may be applied based in part on luminance of the points being mapped. Embodiments apply a reduced dataset representing a gamut boundary. Irregular gamuts may be accommodated
