Established in 1931 and based in Vienna, Austria, the International Commission on Illumination (usually known as the CIE for its French name Commission internationale de l'éclairage, but the English abbreviation is sometimes seen in older papers) is the international authority on light, illumination, color, and color spaces.

Organization
The CIE has seven divisions, each of which establishes technical committees to carry out its program under the supervision of the division's director:
- Vision and Color
- Measurement of Light and Radiation
- Interior Environment and Lighting Design
- Lighting and Signalling for Transport
- Exterior Lighting and Other Applications
- Photobiology and Photochemistry
- Image Technology
Milestones
- Building on the Optical Society of America's Colorimetry Report in the August 1922 issue of the Journal of the Optical Society of America and Review of Scientific Instruments, six years after the OSA's inception, the CIE convened its Eighth Session in 1931, with the intention of establishing an international agreement regarding colorimetric specifications and updating the recommendations made by the OSA based on the developments of the passing decade.[1] The meeting, which was held in Cambridge, United Kingdom, concluded with the formalization of the XYZ color space, standard illuminants A, B, and C. The inspirational 1922 report marked a shift in the treatment of color to a scientific one, defining color in the following terms:[2]
-
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.
