Wouldn't it be better to define the transparency in ConTeXt and use it
for both text and drawing? Like this:
\definecolor [tred] [r=1,g=0,b=0,t=.2,a=1]
\startuseMPgraphic{T}
newpath rc; rc := fullsquare xyscaled (50mm, 50mm);
color col; col := (1.,.1,.1);
drawoptions(withcolor \MPcolor{tred}) ;
draw rc withpen pencircle scaled (2.5mm) ;
label(textext("\setupbodyfont[sans,35mm] \color[tred]{Test}"), (80mm,
50mm)) ;
\stopuseMPgraphic
\defineoverlay[T][\useMPgraphic{T}]
\setupbackgrounds[page][background={foreground,T}]
\startTEXpage[width=200mm,height=200mm]
\stopTEXpage
See ch. 8.2 of the metafun manual.
