Adobe RGB color space

Color representation on computer displays and television screens takes place in defined color spaces. The larger a color space is, the more colors can be represented. One of the better known color spaces is the standard RGB color space( sRGB) defined by Microsoft and Hewlett Packard.

Another RGB color space that features a larger color gamut is the Adobe RGB color space, defined by Adobe in 1998. All color spaces use the CIE color space as a reference color space.

The Adobe RGB color space aims at the CMYK color model for subtractive color mixing used in printers, but taking into account the color representation of displays, which is based on RGB. It is thus an optimization model for converting the RGB color space into a CMYK color space. The Adobe color model includes about 50% of the colors that can be represented in the CIE color model. Adobe RGB is superior to standard RGB especially for cyan and green, but also for yellow and orange tones.

The Adobe RGB color space defines a gamma correction of 2.2, the color temperature for white is 6,500 K, standard illuminant D65, with xy-coordinates of 0.312 and 0.329 in the CIE color space. The xy coordinate values for red are 0.640/0.330, for green 0.210/0.710, and for blue 0.150/0.060. For red and blue, the coordinate values correspond to those of sRGB.
