Use text backgrounds.

\definetextbackground
  [SummaryBackground]
  [frame=off,
   background=color,
   backgroundcolor=gray]

\definehead[summary][section]

\setuphead
  [summary]
  [before=,
   beforesection={\blank\starttextbackground[SummaryBackground]},
   aftersection={\stoptextbackground\blank}]

\starttext

\startsection[title=Knuth]

\input{knuth}

\stopsection

\startsummary[title=Zapf]

\input{zapf}

\stopsummary

\stoptext
