I avoid black washes as well, since it's too intense for most applictaions, prefering a dark-shade of the base colors, heavily-thinned, and adding layers until I get the effect I want.. I top it off with dry-brushing lighter shades of the base for highlights. I use dark grey washes in the collar areas and cuffs, and around caps and hats..
If the figure is going to be standing on dirt, I carry some of the dirt-color up onto its boots to tie it all together using pastels...
