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]

Organization

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

  1. Division 1: Vision and Colour
  2. Division 2: Physical Measurement of Light and Radiation
  3. Division 3: Interior Environment and Lighting Design
  4. Division 4: Transportation and Exterior Applications
  5. Division 6: Photobiology and Photochemistry
  6. Division 8: Image Technology

Division 5 (Exterior Lighting and Other Applications) and Division 7 (General Aspects of Lighting) are inactive today.

Milestones

  • In 1964 the 10° CIE standard observer and its corresponding colour matching functions as well as the new standard daylight illuminant D6500 were added, as well as a method for calculating daylight illuminants at correlated colour temperatures other than 6500 kelvins.
  • In 1976, the commission developed the CIELAB and CIELUV colour spaces, which are widely used today.
  • Based on CIELAB, colour difference formulas CIEDE94 and CIEDE2000 were recommended in the corresponding years.

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."
