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 -- Ing.

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.
