Abstract

Methods, systems and processor-readable media for color balanced compression in dynamic range mistmatched color environments. An input L* can be compensated based on L*in a destination space with respect to shadow colors while configuring a perceptual LUT during a profile phase. Input opponent color components a* and b* can be compressed based on how much L* is compensated to generate newly compressed L*a*b* values. The newly compressed L*a*b* values can be treated as an output L*a*b* to configure the perceptual LUT for color balanced compression thereof. Finally, an operation can be performed for recording in the output LUT, optimized CMYK values with respect to the output L*a*b* to configure the perceptual LUT in an ICC profile and result in the color balanced compression thereof.
