The problem with printing colour negatives onto b+w paper is that the
b+w paper only responds to blue (and depending on the paper, green)
light, and completely ignors the red. Kodak make a special panchromatic
b+w paper for printing from colour negatives, Panalure -- or at least
they did. I used it years ago and it works well.
Note that panchromatic papers such as Panalure are sensitive to
safe-light, so must be handled, exposed and processed in total darkness
or safelight for colour print material. A normal b+w red or orange
safelight will fog the paper.
