Hi, I would like to use transparnt colors in one of the documents. However the resulting color is different with transparent color. Could anyone try the following code twice setting the %-sign in front of the fill-statement: \setupoutput[pdftex] \starttext \setupcolors[state=start] \startuseMPgraphic{tBG} path p ; p := unitsquare xscaled \overlaywidth yscaled \overlayheight ; fill p withcolor \MPcolor{white}; % With normal colors, everything is fine (blue is really RGB(0,0,1) % fill p withcolor transparent("normal",.5,\MPcolor{white}); % This however results in fading of ALL of the colors... \stopuseMPgraphic \defineoverlay[textBG][\useMPgraphic{tBG}] \setupbackgrounds[page][background=color,backgroundcolor=blue] \setupbackgrounds[text][background=textBG] \input tufte \stoptext I would expect that the optical appearance of blue shoud not change after application of the transparent color to the gray areq. Regards Willi
