I never tried to filter it to neutral and I don't recall what filtration I used for this, but I did print some torchlit TMZ shots on RA4 paper filtered to look "torchlight orange" that I was very happy with. Worked great for this application and I can see maybe a blusih/cool cast giving a good effect for snow scenes etc.:
Thanks all so far and especially BMbikerider for the suggestion on starting filtration. As has been said and Roger Cole has showed it, a variation on filtration gives a wide range of tones as well.
