Additive color
An RGB color space is any additive color space based on the RGB color model.
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.
At this writing sRGB is by far the most commonly used RGB color space, particularly in consumer grade digital cameras, because it is "good enough" for most consumer applications, and its design simplifies previewing on the typical computer display. However Adobe RGB is being built into more and more medium range digital cameras, and is favored by many professional graphic artists.
