Charles,
A great thing to work on. Thank you. With regard to tying lighting to atom
type, this is a rare occasion when I will say, "sorry, not going to happen"
-- the lighting effects are generated at a totally different level than atom
effects. By the time those are applied, Jmol is working at the fundamental
level of bits and pixels, not atoms and bond. I'm not optimistic this would
work.
Of course, there are several forms of color blindness. So I would suggest
experimenting more with color and translucency. You might very well come up
with some "user palettes" that are accessibility options for specific forms
of color blindness.
