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?
