Using \MPcolor does it for me. Thank you very much, Aditya :)

You need:
withcolor \MPcolor{maroon}
or (note the quotes)
withcolor "maroon"

newcolor randomcolor;
randomcolor := (normaldeviate, normaldeviate, normaldeviate);
withcolor randomcolor;

[NTG-context] Two questions about color in MetaFun
Hi, list! I have two questions concerning MetaFun:
1st:
What is the correct way to pass a ConTeXt named color (e.g. xwi's "maroon")
to MetaFun. Using (with \usecolors[xwi] loaded in the preamble):
withcolor maroon
does not work. I could copy-paste definitions from ConTeXt sources and do
e.g.
\definecolor [maroon][r=.690196,g=.188235,b=.376471]
but it is unfeasible for complete color schemes. So, is there a better way
to do it?
2nd:
I was trying to do some stuff for my girlfriend using ConTeXt and I tried
to randomize colors in MetaFun using normaldeviate. However, something
interesting happens. The following:
\setuplayout[width=middle]
\setuppagenumbering[state=stop]
\setuppapersize[A10,landscape][A10,landscape]
\starttext
\startuseMPgraphic{cornystuff}
draw outlinetext.f ("\framedtext[frame=off,width=fit,align=middle]{I love
you \\ \CONTEXT}") %\CONTEXT is not my girlfriend, it's just for the example
(withcolor (normaldeviate,normaldeviate,normaldeviate) withpen pencircle
scaled 1/5)
scaled 1 ;
\stopuseMPgraphic
\dorecurse{20}{%
\startplacefigure[location=force,number=no]
\useMPgraphic{cornystuff}
\stopplacefigure
\page[yes]
}
\stoptext
changes the color of every letter. I don't complain (in fact it does look
better), but I still have a question: what should I do if I wanted to
select a random color first and then use it for the entire content? Thanks
in advance.
