Thanks for this snipped, Hans. It looks promising, but I get the
following compile error:
!mplib : mp terminal: >> "\colored [r="
>> 0.74464
! Not implemented: (string)&(known numeric).
<to be read again>
I used the following code:
\starttext
\startuseMPgraphic {1}
numeric r, g, b ;
r := uniformdeviate 1 ;
g := uniformdeviate 1 ;
b := uniformdeviate 1 ;
label(textext("\colored[r=" & r & ",g=" & g & ",b=" & b & "]{Test}"),
origin);
\stopuseMPgraphic
\useMPgraphic {1}
\stoptext
Marco
