I'm no expert, but this seems to work:

\setupcolors [state=start, system=rgb]

\def\bw#1{\framed[background=color,backgroundcolor=black]{\color[white]{#1}}}

Slightly more ConTeXtish \defineframed [WhiteOnBlack] [background=color,backgroundcolor=black,foregroundcolor=white] (I also tend to avoid small lowercase command names, as you could inadvertenly redefine a build-in context macro)

\setuppagenumbering[command=\bw,location={header,margin}] \starttext \input tufte \stoptext
