Postscript/Ghostscript allows to define transparency for a pdf target.

BUT: We build our scores from a lot of symbols and a few postscript functions. Most of the time those symbols overlap. What would be the result if we would use transparent colors for stems, noteheads, ledger lines, flags, accidentals, etc? I think the result would be pretty useless unless your 
intention is to show how we  construct our scores. The attached lilypond source demonstrates how to persuade lilypond to generate a pdf with transparency, and it demonstrates the problem I mentioned.

You invested a lot of work, so the probability is high that there is a real use 
for the feature. Could you be so kind to give an example to a man with a lack 
of imagination?
