White balance woes

Heya,
I was recently browsing through my photos from our high school's production of The Matchmaker. While shooting however, one thing I neglected to take into consideration was my 300D's white balance setting - so most of my photos turned out very yellow under the stage lights. As the sound designer and board op, I had more important things to worry about at the time - like nailing my cues
Anyways, here's one photo in particular thats giving me a hard time to fix in photoshop:
Anyone care to give it a try? For what it's worth, the scene was lit with 3200K Halogen lamps from the front and top with light pink gel filters on the front (Rosco 33?)
Thanks!

I just did two curves adjustments, one on the red channel and one on the RGB channel.
Red - Input: 45 Output: 55
RGB - Input: 75 Output: 56
Im pretty sure I went too far but I hope it looks a bit more natural. I was also wondering if you wanted to achive extra warmth with the filter or are you using it to combat the particular lighting?
(I am not sure on posting other peoples images, I hope this is the right way to do it, feel free to correct me if im wrong anyone)
Cheers, Nigel

Nigel....the down lights being pink are to help keep the people and set from washing out, and to help keep looking alive.....too much front "white" light and all of a sudden everything disappears, totaly washed out......Glad to see it wasnot BROADWAY PINK....Yuuuk!
this is the one I worked on in PS-CS LAB
I could not get the tablecloth any better...but that is caused by the harsh front lights....Source 4's - 750 watt or what were you using for front lights??
Good comp tho.
The curves.

I don't use PS, but with an older version of PSP I got this:
The tool I used in not included in PS. This is a one-click solution that usually works well, as long as one selects the correct area on a pic.
Otherwise, you probably have a color balance correct tool in PS with a color temperature slider. You could try 7000-7500, strength=30, with Remove Color Cast box checked, if those values relate to your editor. It looked the same to me as the above.

Thanks, all making sense now. I was thinking that the filter was on the camera, not the stage lights.

In regards to Art's comment, we were indeed using source 4 instruments in the FOH positions, as well as 1000 watt par64's for down light
Of course no electrician hardly ever runs the lights at full (100%) so That will change the color temp drastically also.
I prefer to shoot under colored lighting as opposed to "white" lights that are changing power.....
Keep up the good work....
Go to your LD and find out what gel colours he was using. Then take a WB off a setpiece you know is white (you should probably be able to find a reference in the props.)
These will give you 2 points of external reference -- the third will be your memory. Try doing the curves in RGB instead of LAB, as RGB is more akin to theatrical lighting.
Also, a board op shouldn't be taking pictures, they should be running the show :P
