✦ Synopsis

Although the CIE states that the 1931 2Њ [xV (l), not, in reality, a consequence of different criteria in their derivation. yV (l), zV (l)] standard observer characteristics and those of the 1964 10Њ [xV 10 (l), yV 10 (l), zV 10 (l)] standard observer were derived from experimental data in the same

way, there are differences. One discrepancy is a difference of 6 nm in the tangent wavelength of the (Y)(Z) line

This CIE system of colorimetry has recently been deon the chromaticity chart, with a corresponding change in scribed in detail 3 and is summarized here. The CIE colorithe minimum wavelength of xV 10 . The reason for this is metric standards (X ), (Y ), (Z ) were derived from the investigated and the two systems are considered. ᭧ 1998 spectral stimuli (R), (G), (B), 4 of wavelengths 700.0,
