chromaticity coordinates, pl
coordinates expressing the quotients of each of a set of three tristimulus values and their sum
Note 1 to entry: As the sum of the three chromaticity coordinates is equal to 1, two of them are sufficient to define a chromaticity.
Note 2 to entry: In the CIE standard colorimetric systems, the chromaticity coordinates are represented by the symbols
Note 3 to entry: The chromaticity coordinates have unit one.
Note 4 to entry: This entry was numbered 845-03-33 in IEC 60050-845:1987.
Note 5 to entry: This entry was numbered 17-145 in CIE S 017:2011.
