Dear Wolfgang,


So this the example now, 


\setuppapersize
[A4]
\starttext
 % hex
 \definecolor[almond][x=EED9C4] 
\definecolor[mysticmaroon][x=AD4379]
\blackrule[color=mysticmaroon,height=3.ex, width=13.50cm]\par
\defineframed
  [Me]
  [background=color,backgroundcolor=almond] \nointerlineskip
\Me[frame=on, corner=rectangular, topframe=off, bottomframe=off, framecolor=mysticmaroon,width=13.50cm] 
%hex
\definecolor[mysticmaroon][x=AD4379]
Hey, \color[mysticmaroon]{Hello}
 \startcolumns[rule=on,n=2,tolerance=verytolerant,color=mysticmaroon]
\color[mysticmaroon]{Thus, I came to the conclusion that the designer of a new
 system must not only be the implementer and first ..\bf D.E. Knuth}
 \stopcolumns

 \stoptext

and after compiling it, I get:

Command Line:   context.exe --synctex=-1 "column.tex"

I've inserted something that you may have forgotten. (See the <inserted text>
above.) With luck, this will get me unwedged.
mtx-context     | fatal error: return code: 1

What I can see is, that there is somethin wrong with the papersize. Don't know why?

Many thanks

Uschi

1. Use "x" as key to set the color with a hey value, while the "h" key works to set the color it is intended for hsv-values.

2. You have to replace "foregroundcolor=..." with "color=...".

3. You have to pass the correct name as argument to the color key but in your example you use an uppercase V in \definecolor but a lowercase v in \startcolumns.

4. Please test your example before you send them to the list because there is a } at the end of the text without a previous {.

Wolfgang
