I used info in this article when I made this VSCode-theme a couple of years ago: https://vscodethemes.com/e/krueger71.crt-themes/crt-amber?la...

I tried to coax all elements in VSCode to use only two colors (background and foreground) with the foreground in only a few different intensities. It might give a CRT-vibe to some.

The theme is due for an update since newer VSCode has elements that aren't styled correctly.
