No, I think the filters were based on an enlarger color temperature of something like ~ 3200K. I can not find *one* iota of information about enlager bulb temperature/ VC filtration from ANY of the paper manufacturers - anywhere.
Certainly they were not derived from a light source with a color temperature THAT high - I thik that a source radiating light at 4500K would have to be something like a carbon arc lamp.

I once analyzed the color "shift" from Ilford MG filters and found them to be substantially different from the suggested correction values in the data sheets. In matching the new color correction values with the dichroic head on my Omega, I had *much* improved results.
