i was messing with the code of a gmic filter i did but something weird happened
Obviously i did some errors but the result is somehow interesting, the filter make apparently most of the image transparent but preserve the highlight and light color as yellow and for misterious reason even the red
obviously may be easily adapted to do the contary, preserve black and i suppose the green and turn the rest semitransparent
Apparently:
just add a black layer under and you will see something close to the original but with stretched contrast except for highlight..and replacing the black BG with a dark optical pattern result become even more interesting

Or as bg layer may be used a dotted version of the original...
or simply as below a more psichedelic pattern

The problem is that i don't know yet why that happens, still that semitransparent layer seems to have a lot of possible use
so i zipped the xcf file with the code i used
Mean that now the controls do not work as intended even if somehow they change the final result
