The color conversion is usually defined through another standardized color space XYZ, and is quite a complicated process.Īs there are more than one RGB color space, you may ask, which colors do you enter in applications like Paint? Professional image and video processing software is aware of color spaces, so a user may specify color space explicitly, but simple software has no such options. Color Profiles (or ICC profiles) have been designed to carefully reproduce the color, by embedding profile into source (image), output (display or printer) and providing conversion rules between them. This representation might be incomplete, so that you may see labels like “87% sRGB coverage” meaning that display may physically represent only 87% of colors from sRGB color space, while others will be usually clamped.Ĭolor reproduction is a great concern for artists, as color distortion might ruin aspects and hide important details when displayed on various displays. Predefined profiles in a monitor allow representing standardized color spaces like AdobeRGB or sRGB on a calibrated device. CRT, LCD, OLED displays also rely on RGB triad to represent a color, but each physical display actually has its own unique RGB color space. AdobeRGB, sRGB and others are color spaces defining different extremes for RGB primaries.

The same is true for all 3 primary components, which absolute values define the range of color values, or coverage, usually displayed as a triangle. While picking a pure green color in a paint program, ask yourself – is it really the very extent of green color you ever seen, or there are more “greener” shades in the world? The correct answer would be no, the green color you see on the screen is not the very extent, although it might be close to what the human eye may distinguish in case of a good monitor.
