Uli,
While they might look like skin tones under a
given illuminant, have you verified that they
spectrally are similar to skin tones?

If not, then can a target that would be representative be constructed ?
For, surely, the chief criterion in
constructing a target should be that capture
quality of the target implies capture quality
in the real world.
Absolutely.
Of course, the question is if this is possible
at all, considering all the possible
complications Eric mentioned. OTOH, I don't
really see how a profile designer that focuses
on scenes rather than targets could avoid all
the metamerism etc. issues that target built
profiles might plague.
In any case, one enhancement of the current
Digital ColorChecker SG (relative to earlier
targets) is that it features a lot of skin tone
color patches. And indeed, it's especially the
skin tones that got much better (= more
realistic) with my ProfileMaker test profiles.
This would argue that it's possible to build a
target that's relevant for real-world colors.
Bye
