If you use that kind of simple graphics, you can avoid this transparency 
hacking by using metafun:

\setupbodyfont[dejavu]

\starttext

\startuseMPgraphic{test}
     pickup pencircle scaled 2mm ;
     draw fullcircle scaled 3cm withcolor darkred  withstacking 1 ;
     draw fullcircle scaled 2cm withcolor darkblue withstacking 2 ;
     draw textext("one")   withcolor darkgreen withstacking 11 ;
     draw textext("two")   withcolor darkgreen withstacking 12 ;
     draw textext("three") withcolor darkgreen withstacking 13 ;
\stopuseMPgraphic

\startTEXpage[offset=.25ts]
     \useMPgraphic{test}{stacking={1,11}}
\stopTEXpage

\startTEXpage[offset=.25ts]
     \useMPgraphic{test}{stacking={2,12}}
\stopTEXpage

\startTEXpage[offset=.25ts]
     \useMPgraphic{test}{stacking={1,2,13}}
\stopTEXpage

\stoptext

It's an already old feature but probably not that well known. If needed 
I can make something similar at the tex end.
