Abstract
We have proved that the application of the tristimulus value Xz seems to be unnecessary.
It can be suggested that the measuring of the tristimulus value Xz should be left and the sign X2
should be defined from the measured value Z on the base of the following connection:
Z
X.",,--
- 5,982
It would be more proper to neglect the use of the tristirnulus value X2 but this would need the total
reconstructing of the CIE colour-system
