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?
The only way that I managed to do this is to draw the chemical twice and to
use overlays (or to trick the bounding box using left=,right=,top=,bottom=).
It would be nice to be able to draw colored bonds, perhaps with the syntax:
\chemical[SIX,rulecolor=blue,SB1,rulecolor=black,SB2..6][]
The problem is that we usually don't mix single tokens with token=val.
(but Hans has broken this rule with an experimental feature: Z1=C, currently
broken as it converts C to lowercase...)
For now, rulecolor= can only be specified in \startchemical or \setupchemical.
Maybe we can discuss this with Hans off-list?
