Also, because each axis is non-linear, it is not possible to create a two-dimensional chromaticity diagram. Also, it is important to understand that the visual representations shown in the ... 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. coach trips from margate kent
