Thanks a lot. But I'm still a bit lost in all the
new commands. I can't figure out how to shade from a
particular colour to transparent.
\starttext
\definecolor [trans-t] [t=1, a=normal]
\startMPpage
path p; p:=fullsquare scaled 5cm;
fill p withcolor \MPcolor{red};
% Works if background colour is known and uniform
path p; p:=fullsquare scaled 3cm;
fill p
withshading("linear", llcorner p, urcorner p)
withcolor \MPcolor{blue} shadedinto \MPcolor{red};
path p; p:=fullsquare scaled 5cm shifted (5cm, 0cm);
fill p withcolor \MPcolor{red};
% Shades to white
path p; p:=fullsquare scaled 3cm shifted (5cm, 0cm);
fill p
withshading("linear", llcorner p, urcorner p)
withfromshadecolor \MPcolor{blue} withtoshadecolor \MPcolor{trans-t};
\stopMPpage
\stoptext
