Is it possible to get a transparent background in a textext()? The following minimal example doesn’t work.

\starttext
\setupMPpage
  [background=color,
   backgroundcolor=gray]
\startMPpage
draw textext("\definecolor[labelbackground][a=0.2,r=1,g=1,b=1]\framed[height=1.2em,background=color,backgroundcolor=labelbackground,foregroundcolor=black]{Text in Label}");
\stopMPpage

\stoptext


Thx.

G

\definecolor[labelbackground][a=1,t=0.2,r=1,g=1,b=1]
