Hello,
suppose having the following code:
----
\startuseMPgraphic{T}
newpath rc; rc := fullsquare xyscaled (50mm, 50mm);
color col; col := (1.,.1,.1);
draw rc withpen pencircle scaled (2.5mm) withcolor %col;
transparent(1, .4, col);
draw thelabel(btex\setupbodyfont[sans,35mm] Test etex, (80mm, 50mm))
withcolor %col
transparent(1, .4, col)
;
\stopuseMPgraphic
\defineoverlay[T][\useMPgraphic{T}]
\setupbackgrounds[page][background={foreground,T}]
\startTEXpage[width=200mm,height=200mm]
\stopTEXpage
----
The rectangle drawn is transparent, which is OK.
But the text "Test" is not, is it fully red; why?
How to specify text to be partially transparent, too?
TIA.
Best regards,
Lukas

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.
