[NTG-context] Color Lost when Using 'texexec' vs 'context'

Hi all, I am using some darkgray in my documents, as in \color[darkgray] foo... which was working out well as long as I was processing my documents with the 'context' command. I recently started using 'texexec' instead, as in texexec --pdf definitions-acronyms-and-abbreviations.tex (which, I understand is preferable) and strangely, all of my darkgray text is now rendered black. Any ideas why the command makes a difference and what to do about it? Regards, Malte. PS: Sorry, for one of my previous emails in which I replied to the full daily digest, which resulted in a very long email to everyone. Won't happen again.
