color as module parameter (mkiv)

[Peter Schorsch <tralalas@freenet.de>]

Hi,

I am trying to pass a tex color as a paramter to a module. I used the
example from the wiki as a base. But as soon I hand over a color
directly it does not work.

Any help is welcome as I am looking forward to hand
in my first module. Are there any rules how and where to hand in a
module for context?

Thanks
P.

--8<---Modul: bgcolor.tex---------------

\startmodule[bgcolor]
\unprotect
\definecolor[grau][s=.35]
\setupmodule[color=grau]
\setupbackgrounds[page][background=color,backgroundcolor=\currentmoduleparameter{color}]
\protect
\stopmodule
\endinput

--8<--tex file itself---------
\setupcolors[state=start]
\definecolor[bordeaux][r=.66]
\usemodule[bgcolor][color=bordeaux]
\starttext
Hello world!
\stoptext
