| Definition: | uniform-chromaticity-scale diagram produced by plotting in rectangular coordinates v against u Note 1 to entry: The CIE 1960 uniform-chromaticity-scale diagram is substantially used for the determination of correlated colour temperature. Note 2 to entry: The CIE 1976 uniform-chromaticity-scale diagram is a modified version of the CIE 1960 uniform-chromaticity-scale diagram, which is equivalent to the (u, 3/2 v) diagram; therefore the (u, v) diagram is equivalent to the (u', 2/3 v') diagram.
