color in before=

color in before=

[Hans van der Meer]

I want to put a color command in a "before" command, that command  
being inserted in a macro.
Something like \setupxyz[before=\color[green]{whatever}]

The problem is that the argument parser gets confused when []- 
expressions are found within the setup.
It is not an option to reprogram everything with {}'s instead of  
[]'s, because then I lose to much of ConTeXt's abilities (apart from  
the nuisance of having to reprogram something that has already been  
done).

I suspect there is no way of sneaking in these []'s inside the  
command? That is the general solution.

My eyes spotted something like \dowithcolor#1#2, but there TeX  
complains about not knowing \od.

Is there a solution to this problem?

yours sincerely,
dr. H. van der Meer

\setupxyz[before={\color[green]{whatever}}]

Thanks, that worked. But it leads to my next question, I am afraid.

When I define:
	\definecolor [brightred][r=0.7, g=.1, b=.1]
then I can use this in \startcolor[brightred]...\stopcolor
according to \meaning brightred being \protected macro \switchtocolor  
[brightred]

Now I am fond of symbolic names and therefore also defined:
		\definecolor [FrameColor][brightred]
Thus being able to use FrameColor as \MPcolor{FrameColor} in MetaFun.
(\meaning says \MPcolor{FrameColor} is \scaledMPcolor 1Framecolor,  
\FrameColor being undefined)

I thought to use \MPcolor{FrameColor} also in
	\startcolor[\MPcolor{FrameColor}]...\stopcolor
or	\startcolor[FrameColor]...\stopcolor
but neither of these worked, nor did
{\switchtocolor[FrameColor]...}\crlf
{\switchtocolor[\MPcolor{FrameColor}]...}\crlf

How can I use FrameColor here to? Without defining extra macros  
around FrameColor, I hope.

This really should have worked:

   \definecolor [brightred][r=0.7, g=.1, b=.1]
   \definecolor [FrameColor][brightred]
   \setupcolors[state=start]
   \starttext
   \startcolor[FrameColor]Bright Red\stopcolor
   \stoptext


Cheers, taco

Please forget about the posting below.
I messed up something else (having to do with not enabling the  
appropriate mode selections in other files).
Sorry.
