tristimulus values
The values of the three standard or matching stimuli necessary to provide a match with the light under trial, in a specified trichromatic system.
chromaticity coordinates
Proportions of standard primaries (tristimulus values) required for a color match; ratios of each tristimulus value of a color to their sum. In the CIE colorimetric system, designated X, Y and Z.
