An RGB color space is any additive color space based on the RGB color model. A color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four values or color components (e. ... The RGB color model utilizes the additive model in which red, green, and blue light are combined in various ways to create other colors. ...

RGB is shorthand for Red, Green, Blue.

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 than sRGB. Adobe has recently developed another color space called Adobe Wide Gamut RGB, which is even larger, in detriment of gamut density. Computer graphics (CG) is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world. ...

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. 2004 is a leap year starting on Thursday of the Gregorian calendar. ...

RGB spaces are generally specified by defining three primary colors and a white point. In the table below the three primary colors and white points for various RGB spaces are given. The primary colors are specified in terms of their CIE chromaticity coordinates (x,y). A white point is one of a number of reference illuminants used in colorimetry which serve to define the color white. Depending on the application, different definitions of white are needed to give acceptable results. ... CIE is an acronym which can stand for Córas Iompair Éireann, Irish transport company; the International Commission on Illumination; the postnominal of a Companion of the Order of the Indian Empire; Cambridge International Examinations, an international examination board. ...
