CIE 1931 xy chromaticity diagram showing the gamut of the wide-gamut RGB color space and location of the primaries. The D50 white point is shown in the center.. The wide-gamut RGB color space (or Adobe Wide Gamut RGB) is a color space developed by Adobe Systems, that offers a large gamut by using pure spectral primary colors. [1]
It is able to store a wider range of color values than sRGB. The Wide Gamut color space is an expanded version of the Adobe RGB color space, developed in 1998. As a comparison, the Adobe Wide Gamut RGB color space encompasses 77.6% of the visible colors specified by the Lab color space, whilst the standard Adobe RGB color space covers just 50.6%.
Adding a specific mapping function between a color model and a reference color space establishes within the reference color space a definite "footprint", known as a gamut, and for a given color model, this defines a color space. For example, Adobe RGB and sRGB are two different absolute color spaces, both based on the RGB color model.
RGB color spaces are well-suited to describing the electronic display of color, such as computer monitors and color television. These devices often reproduce colours using an array of red, green, and blue phosphors agitated by a cathode-ray tube (CRT), or an array of red, green, and blue LCDs lit by a backlight, and are therefore naturally ...
The D65 white point is the existing standard for common sRGB and devices (Adobe RGB also uses D65). Display P3 uses the sRGB transfer curve, which is approximately equivalent to a gamma of 2.2. [19] Display P3's gamut is approximately 50% larger than sRGB in volume and 25% in surface. [20]
In color reproduction and colorimetry, a gamut, or color gamut / ˈ ɡ æ m ə t /, is a convex set containing the colors that can be accurately represented, i.e. reproduced by an output device (e.g. printer or display) or measured by an input device (e.g. camera or visual system). Devices with a larger gamut can represent more colors.
This so-called gamut mismatch occurs for example, when we translate from the RGB color space with a wider gamut into the CMYK color space with a narrower gamut range. In this example, 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.
Rec. 2100 specifies the use of the RGB, YCbCr or IC T C P signal formats for HDR-TV. [5] IC T C P is a color representation designed by Dolby for HDR and wide color gamut (WCG) [92] and standardized in Rec. 2100. [5] IPTPQc2 with reshaping is a proprietary format by Dolby and is similar to IC T C P. It is used by Dolby Vision profile 5. [45]
