this is tricky; context has a color stack, but the text and mp stuff
work independently (in mp there is no symmetry in color handling); i can
imagine a different handling of mp colors, but this will slow down
things (comes down to pushing and popping colors on the context color
stack and such)
in this situation, i think that the best we can do is to revert to the
current color, so i patched things a bit:
test case:
\setupcolors[state=start,textcolor=red]
\starttext
red
\color[green]{green
\startMPcode
label(\sometxt{green\color[blue]{blue}green}, origin)
withcolor red;
draw fullcircle scaled 1cm xscaled 2;
\stopMPcode
green}
red
\stoptext

hm, i'll add the inclusions
(here it fails anyway doe to some
clearboxes->clearboxes
.clearb_(h);
clearboxes->clearboxes
.clearb_(h);
clearboxes->clearboxes
.clearb_(h);
clearboxes->clearboxes
.clearb_(h);
clearboxes->clearboxes
no time to look into that now (i never use boxes)
