Abstract
In accordance with one aspect of the present disclosure, apparatus are provided that include a color data conversion subsystem configured to convert color data in order to produce device-dependent output color separation data. The color data conversion subsystem has been configured by gamut mapping including providing a gamut in a hue-based color space and applying color distance adjustments to the hue-based color space. A hue dependent lightness preservation operation can also be part of the subsystem.
