When shooting color negative materials without filtration
under lighting color they weren't intended for, if you do not
"overexpose" when unusual filtration is used in printing
to compensate for the light color, you may have what amounts
to underexposure of some film color layer(s). If you want good,
neutral-looking dark tones, you must give the film sufficient
exposure to make that possible... No free lunch: you either
take the speed hit when shooting with a correction filter,
or you take it with the exposure compensation needed for
good color balancing later during printing.
