The CIE 1931 colour space chromaticity diagram with wavelengths in nanometers. The colors depicted depend on the color 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, which was founded in 1900, and is today based in Vienna, Austria.


The CIE has six active divisions,[1] each of which establishes technical committees[2] to carry out its program:

Two divisions are no longer active:[citation needed]

The President of the CIE from 2019 is Peter Blattner from Switzerland.[9]

CIE publishes Technical Reports (TRs), International Standards (ISs) and Technical Notes (TNs). International Standards (ISs) are often further developed as dual standards with the ISO or IEC.[10]

The report defined colour as follows: "Color 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."
