[NTG-context] ppchtex, color and mkiv
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!

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?

[NTG-context] ppchtex color
No, ppchtex is not dead...
I would like to use color.
1. color= and rulecolor= does not appear to be implemented (mkiv)...
2. how can one change the color of the bonds?
3. using \color[red]{} causes the text to be offset.
minimal example:
\setupcolors[state=start]
\usemodule[chemic]
\starttext
\startchemical
\chemical[ONE,SB,Z0][C]
\stopchemical
\startchemical
\color[red]{\chemical[ONE,SB,Z0][C]}
\stopchemical
% text C is offset...
\startchemical
\chemical[ONE,SB,Z0][{\red C}]
\stopchemical
% OK, but I would like to draw the bonds as well in red.
\startchemical[color=red]
\chemical[ONE,SB,Z0][C]
\stopchemical
% C is red in mkii, black in mkiv
\startchemical[rulecolor=red]
\chemical[ONE,SB,Z0][C]
\stopchemical
% bonds are black, C is red in mkii, black in mkiv
\stoptext

add a % after the } (maybe we should ignore endofline, i.e. make a mkiv
variant and extend/maintain that)

setting happened at the outer level (ok, that's broken now but we can
fix that later); so now, each formula must have the settings; when i
have time i'll make a mkiv variant so that we can upgrade (i don't want

don't need to upgrade that)
