I'm not quite sure I understand what you're trying to do, so this is a shot in the dark: instead of low-level trickery, you could use ConTeXt modes: \startmode[A] \definecolor [mycolor] [g=1] \stopmode \startmode[B] \definecolor [mycolor] [r=1] \stopmode You can then set \enablemode[A] in your file or pass the mode on the commandline: texexec --mode=A HTH Thomas ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
