How about this, Steve?

I don't know how to put this. The "exact" complementary color is what is
exactly opposite the filter color, but of course the filter affects the
brightness of the "near-by" colors, too, but to a lesser extent.

You are right: "one advantage of colour capture is that the range of
adjustments that can be made post  capture is significantly greater than
those that can be made with B&W film.". However, the "acutance", or
sharpness, of B&W films is higher than that of color films, and I believe
that I have noticed that their local value contrast is better, too.

How about this:

Ukko

Thanks for this.  I guess what I am searching for is an understanding of
what these filters do to the RGB space hitting the film plane eg more red,
less blue, little less green etc.  That is, an expression of the filter in
terms of RGB rather than ³enhances contrast² etc.  Does this make sense?
