I was an expert at masking and printing Ciba - and yes, masking was essential not only for contrast control but also taming the serious hue idiosyncrasies. I soon learned to dance with the medium rather than fight with it. If you wanted something capable of being controlled, it was dye transfer. CN film had their own skewed color and contrast characteristics built-in mainly for sake of portraiture. Both color neg films and RA4 paper have progressively come quite a ways in recent years, and some of the old stereotypes no longer apply. I'm able to make chromogenic prints which even highly experienced pro lab owners can't distinguish from chrome color work. Supplemental masking is often necessary for that level of hue control, as well as correct light balancing filtration at the time of the shot. But due to the virus epidemic, I'm not doing any color printing this season, since it can be a bit irritating to the respiratory system in a way ordinary b&w darkroom work is not. But turning color negs into meaningful color slides would be a difficult task, unless inverting the color via a scan and then using an expensive lossy film recorder option on chrome slide film. I think PE was referring to the antique method of shooting separate tricolor negatives on panchromatic BLACK & WHITE film, making three contact b&w interpositives from these, and using three aligned carbon arc projectors, respectively themselves having RGB filters in place. That could still be done, but color film itself is not even involved.
