Adobe RGB colour space

The aim of a colour space is to ensure that a colour produced by a colour model is accurately reproduced when displayed on-screen or digitally printed. The Adobe RGB (1998) colour space is an RGB colour space developed by Adobe Systems, Inc.

About the Adobe RGB colour space
  • The Adobe RGB (1998) colour space is designed to encompass the colours that can be reproduced by CMYK colour printers.
  • When the RGB colour model is used on a modern computer screen, the Adobe RGB (1998) colour space aims to reproduce roughly 50% of the range of colours that an observer is capable of seeing in ideal conditions.
  • The Adobe RGB (1998) colour space was developed to improve on the gamut of colours that could be produced by the earlier sRGB colour space, primarily in the reproduction of cyan-green hues.
About colour spaces
  • A colour space aims to accurately define the relationship between any selected colour and how it will be perceived by the human eye when it is reproduced by a specific digital display, printer or paint mixing machine.
  • The Pantone colour collection defines its colour space by:
    • Establishing a set of inter-related colour swatches.
    • Giving each swatch a name or code.
    • Calibrating a paint machine (or other types of equipment) to accurately reproduce the colour of each swatch.
  • 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.
  • Digital colour spaces are used to define the range (gamut) of colours to be output to digital screens and printers.
  • When a colour space is to be matched with a specific device such as a projector or printer, a colour profile is used to ensure end-to-end color management.
  • A colour profile is a program that allows a piece of equipment to know how to handle and process the information it receives so that it can produce the intended colour output.
