Ken,
I just come back from the CIE Expert Symposium in Ottawa, last week, and the
V-Lambda error has propagated into the 1931 2 degree CMF. So much for those.
And from the talk of the presenters and the questions from the "floor", the
1964 Observer is not that hot either. Apparently, the best CMF that were
ever established by color scientists were those by Stiles and Burch (1955)
2-deg, RGB Color Matching Functions. I'd really like to have the option in a
CMS to use different sets of Color Matching Functions. Currently, only
argyll allows such a choice. I think the same way some profilers allow us
the choice of illuminant, so should they allow the choice of CMF instead of
the regular 2 degree CMF. If the match is better, personally, I don't really
care for one set of CMF or another.
