This CIE Standard specifies the method of calculating the coordinates of the CIE1976 L*u*v* colour space including correlates of lightness, chroma, saturation andhue. It includes two methods for calculating Euclidean distances in this space torepresent the relative perceived magnitude of colour differences. It also specifies themethod of calculating the coordinates of the u',v' uniform chromaticity scale diagram.
The Standard is applicable to tristimulus values calculated using the colourmatchingfunctions of the CIE 1931 standard colorimetric system or the CIE 1964standard colorimetric system. The Standard may be used for the specification ofcolour stimuli perceived as belonging to a reflecting or transmitting object, where athree-dimensional space more uniform than tristimulus space is required. Thisincludes self-luminous displays, like cathode ray tubes, if they are being used tosimulate reflecting or transmitting objects and if the stimuli are appropriatelynormalized. The Standard, as a whole, does not apply to colour stimuli perceived asbelonging to an area that appears to be emitting light as a primary light source, orthat appears to be specularly reflecting such light. Only the u',v' chromaticity diagramdefined in Section 4.1 and the correlates of hue and saturation defined in Section 4.3apply to such colour stimuli.
