WebJul 7, 2014 · Since it was very difficult to represent a three-dimensional space graphically, a two dimension diagram is known as chromaticity diagram CIE 1931 xy where chromaticity coordinates x,y are obtained by normalization x = X/(X + Y + Z); y = Y/(X + Y + Z) allowing dispensed with the third coordinate z since z = 1 − x − y. Furthermore, as in the ... WebPractically, this observer can be used for any field of view smaller than 4°. For a 10 ° field of view, the CIE specifies another set of color matching functions x 10 (λ), y 10 (λ) and z (λ) 10.
