of a different brand that is slightly more orange, and there will be
slightly different gamut, since the set of all colors that can be pro-
duced with the three lights will be changed (Fig. 1.7).
An LCD display can be thought of as a grid of thousands of little
red, green, and blue light bulbs, each with their own dimmer switch.
The gamut of the display will depend on the three colors used for the
red, green and blue lights. A wide-gamut display will have very satu-
rated, “pure” light colors, and thus be able to display very saturated,
deep colors.
RGB is a convenient color model for computer graphics because
the human visual system works in a way that is similar—though not
quite identical—to an RGB color space. The most commonly used
RGB color spaces are sRGB and Adobe RGB (which has a significantly
larger gamut). Adobe has recently developed another color space
called Adobe Wide Gamut RGB, which is even larger, in detriment to
gamut density.
