Red and yellow filters and a polarizer are enough for me. Some other photographers use more filters. If your normal exposure for a daylight landscape is 1/50 second without a filter, the yellow filter may require about 1/25 of a second, depending on which of the several densities it is. A red 25 or A filter might require 1/4 or 1/8 second exposure.

I agree that yellow, red, and polarizing filter will handle 90% of your black and white work.

If you do portraits with hot lights a blue filter will hell minimize men's 5 o'clock shadow. A soft filter for the ladies and you are at 99% of your B&W filter needs.

The only thing to add is that old polarizing filters tend to be junk!

A blue filter will do some rather bizarre and unflattering things to portraits. I won't
describe that. Just try it ! If you want "more masculine" male portraits, try a green
filter. A blue filter will also mimic early landscape appearance cuz it mimics the old
orthochromatic films. BTW, "Blue" doesn't mean a blue color correction filter, like
the Wratten 80 series. "Blue" means a deep blue black & white contrast filter, such
as the Wratten 47 series. "Wratten" is a good search term. Do it.

I'm not sure I've ever used a polarizer for B&W. Certianly not for skys,
cuz orange or red does a hugely better job. Maybe it could be needed
someday to beat reflections, but reflections are important elements
that "spark up" the tonality of BW. Usually, if you're being troubled by
reflections trying to shoot something behind glass the angles are more
often than not all wrong for effective polarizer use.

Can't hurt to acquire a polarizer anyway, cuz you're likely to shoot a
whole lot of RGB that can benefit from reduced color-veiling glare.
