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.
Organization
The CIE has six active divisions,[1] each of which establishes technical committees[2] to carry out its program:
- Division 1: Vision and Colour [3]
- Division 2: Physical Measurement of Light and Radiation [4]
- Division 3: Interior Environment and Lighting Design [5]
- Division 4: Transportation and Exterior Applications [6]
- Division 6: Photobiology and Photochemistry [7]
- Division 8: Image Technology [8]
Two divisions are no longer active:[citation needed]
- Division 5: Exterior Lighting and Other Applications
- Division 7: General Aspects of Lighting
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]
Milestones
- In 1924 it established the standard photopic observer defined by the spectral luminous efficiency function V(λ), followed in 1951 by the standard scotopic observer defined by the function V’(λ).
- standard observer with the corresponding color matching functions, and standard illuminantsA, B, and C.
- In 1964 the 10° CIE standard observer and its corresponding color matching functions as well as the new standard daylight illuminant D6500 were added, as well as a method for calculating daylight illuminants at correlated color temperatures other than 6500 kelvins.
- In 1976, the commission developed the CIELAB and CIELUVcolor spaces, which are widely used today.
- Based on CIELAB, color difference formulas CIEDE94 and CIEDE2000 were recommended in the corresponding years.

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."
