Hi, this is impossible using per channel cLUTs, since you need to move the chromaticities of the primaries, and that involves mapping a pure color to a combination of colors. This is why some wide gamut displays have an sRGB emulation mode. Your alternative is to do the mapping in your application. Note that while you can apply a source to destination transformation using CPU based CMM's (ie. Argyll's imdi, or lcms), you could also use OpenGL to apply a matrix profile or even a full 3D device link, using texture lookups. Graeme Gill.
