chromaticity coordinates

ratio of each of a set of 3 tristimulus values to their sum

Unit: 1

NOTE 1 As the sum of the 3 chromaticity coordinates is equal to 1, 2 of them are sufficient to define a chromaticity.

NOTE 2 In the CIE standard colorimetric systems, the chromaticity coordinates are represented by the symbols *x*, *y*, *z* and *x*_{10}, *y*_{10}, *z*_{10}.
