In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space). Setting Y as luminance has the useful result that for any given Y value, the XZ plane will contain all possible chromaticities at that luminance. WebFigure 8 shows a series of NPL (National Physical Laboratory) ceramic primary color standards measured on a LAMBDA 650 with a 150 mm integrating sphere with an 80angle at the reflectance port. The spectra are traceable to interna- tional standards such as CIE, ASTM, ANSI, DIN and EN.
