Almost all of the work has already been done by other people for other text editors. Porting a theme requires copying files from another project and writing a tiny bit of glue around it. The author of a niche terminal emulator I'm using on small systems was able to add around a hundred themes this way in a short amount of time. Sadly, he wasn't able to raise $7.6k×100 for all that thankless work.
