RGB Colour Spaces

They refer to any Colour Space based on the RGB Colour Model.

An RGB colour space is defined by Chromaticity coordinates of red, green and blue additive primaries, the White Point which is usually defined by a Standard Illuminant and the Transfer Function which is also known as the Tone Response Curve or Gamma.

The primary colours are often specified using their xyY chromaticity coordinates, although the u',v' coordinates from the UCS chromaticity diagram may also be used.
