Hi Willi, all,
Thank you for your answer but it doesn't work... I need it quickly, so
I've a solution but it's not, hum, very clean since I don't know
metapost very well:
\def\followtokens#1%
{\vbox\bgroup
\forgetall
\dontcomplain
\startMPenvironment
Hi Renaud,
you can define a color with
\definecolor[brown] [r=.9,g=.8,b=0.6]
in your MEATPOST code you can say things like
drawoptions(withcolor \MPcolor{brown}) i.e. that all will be
drawn in borwn
draw ... withcolor \MPcolor{brown} i.e. append the color to the
drawing
