Perceptual remapping

The human eye is sensitive to the relationships between colors. Perceptual mapping alters all the colors in the original color space to bring them into the gamut of the destination color space, but preserves the relationships between the colors. As the rela­tionships are preserved, the change in colors will hardly be perceivable.
