Re: Semi-transparent color in Lilypond

[Rupert Snook]

Thanks Patrick and Harm for the suggestions! These could work as workarounds, but still not exactly what I'm after. I'm looking for a color that has an opacity / transparency channel, and this channel could be set between 0% (fully transparent) and 100% (fully opaque). 

If that's not possible, maybe a work around could be to import a pre made graphic that was already semi-opaque.

There's at least a workaround in the lsr to give the illusion of a background color: http://lsr.dsi.unimi.it/LSR/Snippet?id=699.
