RGB color spaces information


1931 CIE chromaticity diagram showing some RGB color spaces as defined by their chromaticity triangles.

RGB color spaces are additive colorimetric color spaces[1] specifying part of its absolute color space definition using the RGB color model.[2]

RGB color spaces are commonly found describing the mapping of the RGB color model to human perceivable color, but some RGB color spaces use imaginary (non-real-world) primaries and thus can not be displayed directly.

Like any color space, while these use the RGB color model to describe the space, it is not mandatory to use that model to signal pixel color values; broadcast color spaces like NTSC, PAL, Rec. 709, Rec. 2020 additionally describe a translation from RGB to YCbCr and that is how they are usually signalled.
