From a thread on this list (May 2009:
http://archive.contextgarden.net/message/20090512.132914.5c29b5f4.en.html)
I gather that whereas colouring a whole molecule works fine, colouring
groups within a chemical structure is not yet fully implemented in mkiv.
Is that still correct?
Putting colour on atoms works with {\blue C} etc. or "\defineprocessor
... etc. chemred->C" etc.. However, I couldn't find a way to colour the
bonds belonging to the group. Is there one?
ppchTEX does a superb job and I hope that the most useful features will
be implemented in the near future in mkiv!
