General principles and methods

Colorimetry - CIEDE2000 Colour-difference formula Ingestion-build-232773 BS EN IEC 60601-2-39:2019 supersedes1 Scope This CIE International Standard specifies the method of calculating colour differences according to the CIEDE2000 formula. The Standard is applicable to input values of CIELAB L*, a*, b* coordinates calculated according to ISO 116644: 2008(E) CIE S 014 4 E: 2007. The Standard may be used for the specification of the colour difference between two colour stimuli perceived as belonging to reflecting or transmitting objects. This includes
