For a purely analog method, get yourself a set of Wratten blue filters and peer through those until you see one that gets rid of the yellow. Then use that filter.
I didn't find anything for Photoshop but I did find a plug-in for GIMP that is supposed to do color temperature conversion, if you don't mind digital. Install GIMP from gimp.org if you don't already have it, then go to http://registry.gimp.org/node/73#attachments and download colortemp.scm. Put it in the C:\Program Files\GIMP-2.0\share\gimp\2.0\scripts folder, then if GIMP is already running, restart it, otherwise start GIMP and load up your image. You'll find the color temperature conversion under Filters->Colors->Color Conversion. Once you have the color the way you like it, convert the color temps to their MIRED values, subtract one from the other, and there's your filtration.
