Colour space

A colour space refers to a method used to organize the relationship between a range of colours in a recognisable and reproducible way.

About colour spaces
  • A colour space can be defined by assigning a set of colour swatches with names or numbers. This is the type of space used by the Pantone colour collection.
  • When an artist chooses a limited number of oil paints to add to their palette they establish a colour space within which they plan to work.
  • A digital colour space is defined mathematically or programmatically to produce a range of inter-related colours each with its own colour value.
  • Digital colour spaces are often used to define the range of colours that can be produced by a particular device (eg. printer or projector) or file type (eg. JPEG file).
About the Adobe RGB colour space
  • The Adobe RGB (1998) colour space is designed to encompass the colours that can be output by CMYK colour printers.
  • When the RGB colours model is used on a modern computer screen, the Adobe RGB (1998) colour space encompasses roughly 50% of the range of colours seen by an observer.
