Glad to help out!
Mixed lighting is always a pain to get right on skin tones. Halogen lamps mixed
with uncalibrated chandelier .. I'm amazed you got as good as you have! Given
two light sources like that, I usually don't bother with color at all ...
neither film nor digital sensors can cope well with such variant lighting. Our
eyes have this amazing image processing engine backing them up ... film and
sensor don't have a chance compared to that.
That, sadly, is just how it is. It's what all that training in photo school is
designed to teach photographers: how to avoid lighting like that, and how to
fix it before making the photos when it's unavoidable. :D

Thanks for all, Godfrey. I did some additional tweaking after I wrote my
question, and I came up with something very similar to your version.
It puzzled me that in both our corrected versions, the young woman appears
paler than she actually is. She's of Asian ancestry, and her face coloration
actually looks the most correct in the overall too-warm original version. One
issue may be mixed light--the chandelier out of view to the right of the
picture puts out cooler light than the halogens, and that may be skewing the
color temperature of the face higher. Also, most non-incandescent lights
output discrete frequency bands rather than a broad spectrum. The dyes in our
retina are not the same as the dyes in camera sensor filters, and they may
respond a bit differently.
