適用范圍：This CIE Standard specifies the method of calculating the coordinates of the CIE 1976 L*a*b*colour space including correlates of lightness, chroma and hue. It includes two methods forcalculating Euclidean distances in this space to represent the perceived magnitude of colourdifferences.The Standard is applicable to tristimulus values calculated using colour-matchingfunctions of the CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetricsystem. The Standard may be used for the specification of colour stimuli perceived asbelonging to a reflecting or transmitting object, where a three-dimensional space moreuniform than tristimulus space is required. It does not apply to colour stimuli perceived asbelonging to an area that appears to be emitting light as a primary light source, or thatappears to be specularly reflecting such light. This Standard does apply to self-luminousdisplays, like cathode ray tubes, if they are being used to simulate reflecting or transmittingobjects and if the stimuli are appropriately normalized.
