CIE

CIE (Commission International de l’Éclairage) International Commission on Illumination; Vienna (Austria)-based commission for issuing photometric and colorimetric recommendations on which the relevant ISO standards for many different fields of application are based, e.g. standard illuminants (D50, D65, A), standard observers (2°, 10°) and color spaces (CIEXYZ, CIELAB, CILUV) including color difference formulae. As in the ISO, there are also Divisions here with Technical Committees (CIE TC) which prepare sector-specific standards. The most important Divisions for color communication are 1 “Vision & Color” and 8 “Image Technology”.
