Hans direct me to 

http://minimals.contextgarden.net/current/context/test/doc/context/tests/mkiv/metapost/plugins-004.tex

fill p
    withshading("linear", llcorner p, urcorner p)
    withcolor \MPcolor{red} shadedinto \MPcolor{blue}
    withtransparency(1,.5) ;

This works, but  I want  "screen" interaction between
background and transparent object, but it looks like the first
parameter has no effect (I put there "screentransparent" or some
another numbers). 

Thanks!
