Hi,
The next beta will support this (for mp lovers)
\definecolor[maincolor] [r=.5]
\definecolor[extracolor] [g=.5]
\definecolor[anothercolor][b=.5]
\definecolor[morecolor] [s=.8]
\startMPpage
fill fullcircle scaled 10cm withcolor "maincolor" ;
fill fullcircle scaled 9cm withcolor "extracolor" ;
fill fullcircle scaled 8cm withcolor complementary "anothercolor" ;
fill fullcircle scaled 7cm withcolor complemented "anothercolor" ;
fill fullcircle scaled 6cm withcolor "morecolor" randomized 1 ;
fill fullcircle scaled 5cm withcolor "morecolor" randomized 1 ;
addbackground withcolor
.5[resolvedcolor("morecolor"),resolvedcolor("extracolor")] ;
\stopMPpage
So, in many cases you can use strings instead of \MPcolor{...}.
