The CIE 1931 colour space chromaticity diagram with wavelengths in nanometers. The colours depicted depend on the colour space of the device on which the image is viewed.

The International Commission on Illumination (usually abbreviated CIE for its French name, Commission internationale de l'éclairage) is the international authority on light, illumination, colour, and colour spaces. It was established in 1913 as a successor to the Commission Internationale de Photométrie and is today based in Vienna, Austria. The President from 2015 is Yoshihiro Ohno from the US.[1]


The CIE has eight divisions, each of which establishes technical committees to carry out its program under the supervision of the division's director:

  1. Vision and Colour
  2. Measurement of Light and Radiation
  3. Interior Environment and Lighting Design
  4. Lighting and Signalling for Transport
  5. Exterior Lighting and Other Applications
  6. Photobiology and Photochemistry
  7. General Aspects of Lighting (Inactive)
  8. Image Technology

The report defined colour as follows: "Colour is the general name for all sensations arising from the activity of the retina of the eye and its attached nervous mechanisms, this activity being, in nearly every case in the normal individual, a specific response to radiant energy of certain wave-lengths and intensities."
