I have stumbled upon a fair method of doing global color changes in PS.
Find something in the image that should just be white.  Say zone 1.5.  Using
the levels dialogue box there are three droppers available.  If you choose
the white one(the one on the right) and put it on the area you determined to
be just white and click the mouse with the dropper engaged it not only sets
your white point it sets and even color balance for the image.  Also useful
is to open the info box which will give you the 8 bit numbers for wherever
the dropper is.  A pure white should be 0 in all three colors.  The
percentage variance is a good guide to what to change if you use the hue or
color balance commands.
