Page "Color management" Paragraph 14

Since different devices don't have the same gamut, they need some rearrangement near the borders of the gamut.

Some colors must be shifted to the inside of the gamut, as they otherwise cannot be represented on the output device and would simply be clipped.

For instance the dark highly saturated purplish-blue color of a typical computer monitor ’ s “ blue ” primary is impossible to print on paper with a typical CMYK printer.

The nearest approximation within the printer ’ s gamut will be much less saturated.

Conversely, an inkjet printer ’ s “ cyan ” primary, a saturated mid-brightness greenish-blue, is outside the gamut of a typical computer monitor.

The color management system can utilize various methods to achieve desired results and give experienced users control of the gamut mapping behavior.
