Monitor manufacturers use terms like "5000K (warm white)" and it means
nothing. I once bought the first Barco 29" monitor for $29,000 (!) and
Barco tech reps came to calibrate it. They calibrated for D50, and the
monitor appeared extremely red compared to a GTI 5000K light box. A
5000K light box actually looks quite blue compared to standard
fluorescent lighting. I had to reset the Barco to 6500 K to get it to
match the light box.
Using Eye-One Share you can use the Eye-One to read ambient light
temperature and color rendering index. However, I still think the best
method is to make a proof from a known image, place it on your high
quality D50 light box with properly burned in tubes(but not too old!)
and tune your profile to match the view of your proof on the light box.
I know this is not very scientific, but after 20 years as a retoucher,
it's the only thing I can count on.

It requires a good bit of time in a dark room to adapt to the yellow of
a D50
monitor. If you are displaying this converted file in a situation where
cooler (and possibly brighter) whites are in your field of view, then
yes, D50 will
look quite yellow. D50 *is* quite yellow.
