Home > RGB color space

RGB is shorthand for Red, Green, Blue.

RGB is a convenient color model for computer graphics because the human visual system is also an RGB color space. The most commonly used RGB color spaces are sRGB and Adobe RGB, which has a significantly larger gamut than sRGB. Adobe has recently developed another color space called Adobe Wide Gamut RGB, which is even larger, in detriment of gamut density.

As of 2004, sRGB is by far the most commonly used RGB color space, particularly in consumer grade digital cameras, because it is considered adequate for most consumer applications, and its design simplifies previewing on the typical computer display. Adobe RGB is also being built into more medium-range digital cameras, and is favored by many professional graphic artists.
