ABSTRACT:
A method, system, and computer-readable storage medium are disclosed for color conversion of a digital image. The digital image comprises a source set of pixels. A perceptual distance may be determined between the source set of pixels and a respective destination set of pixels for each of a plurality of rendering intents. A rendering intent corresponding to the smallest perceptual distance may be selected automatically. The source set of pixels may be converted to an output set of pixels using the selected rendering intent.
