space of another device. This remapping is done according to a specific remapping method, also
known as rendering intent. There are four remapping methods or rendering intents:
• Perceptual remapping on page 194
• Saturation remapping on page 194
• Relative colorimetric remapping on page 195
• Absolute colorimetric remapping on page 196
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.
Figure 83: Perceptual remapping rescales the original gamut (A) within the gamut of the destination color
space (B), but preserves the relationships between colors.
Saturation remapping
Reproduces the original image color saturation (vividness) when converting into the target device's
color space. In this approach, the relative saturation of colors is maintained from gamut to gamut.
