For certain presentations, I would like to have the ability to chromakey in GNOME. I was wondering if anyone knows of any utilities that would enable me to essentially “greenscreen” certain colors of my windows (particularly the background color of my terminal) and have it become fully transparent or transluscent. Is this something that I can do through a shell script or would it be available through an extension?
That sounds so much like an XY problem:
If it is about making a terminal transparent (why is another question), quite a few terminals have that as a setting, maybe a hidden one.
Thanks for responding! I am interested in chromakey not only for use with the terminal (ghostty can do “some” level or chromakey but it is finicky with neovim running), but also for use with blender, so i can isolate a particular shape based on a color and keep it on the screen to perform demonstrations with it…
