The interesting thing about filters, without going into the values found in
the spectrum as light strikes the film plane, is that they emphasize [make
dark in B&W photography] the same color as that which the filter is fixed
onto the lens.
The best color besides yellow, #8, #11, #15 (a sort of orange looking
filter, actually Amber) or the #43 Blue. It is that latter one that can
help in deep canyons or valleys, and making the sky dark.
