Colour space

  • A colour space frames the range of colours that an artist, designer or technician has available to work with.
  • A colour space may aim to restrict the number of colours or establish the widest possible gamut to work with.
  • A colour space is partly predetermined by factors such as the colour theory and the colour model underpinning a workflow.
  • Colour spaces are an important part of colour management and are particularly useful when working with a range of equipment across a digital environment.
  • Digital colour spaces are commonly used to select and work with a range of colours that can be displayed and output to digital screens and printers in a consistent or predictable way.
  • When a selected colour space is to be matched with a specific digital device such as a projector or printer, the type and model can be specified during the editing process.
  • When the future handling of an image is uncertain, colour profiles dedicated to sRGB or Adobe RGB can be added to a digital file to ensure accurate colour reproduction.
  • A colour profile is a program that allows a piece of equipment such as a digital printer to know how to handle and process the colour information it receives so that it produces the intended colour output.
