Let us first try a simple background, then we go to columnsets:


% output=pdf
\mainlanguage[de]
\setupcolors[state=start]

\definetextbackground[wichtig]
        [backgroundcolor=lightgray,
         location=paragraph,
         frame=off,
         backgroundoffset=5pt,
         ]
\starttext
         
\starttextbackground[wichtig]
\input tufte         
\stoptextbackground
\stoptext


Or a somewhat more complicated one:

% output=pdf
\mainlanguage[de]
\setupcolors[state=start]
\definetextbackground[wichtig][]
\startuseMPgraphic{mpos:par:columnset}
   for i := 1 upto nofmultipars :
    linear_shade(multipars[i] enlarged 5pt cornered 20pt,1,
                  \MPcolor{middlegreen},\MPcolor{lightgreen}); 
   endfor ;
\stopuseMPgraphic
\starttext
\starttextbackground[wichtig]
\input tufte         
\stoptextbackground
\stoptext


Do they come out right?
