This is a super-rudimentary utility to generate a ghostty (https://ghostty.org/) terminal colors theme, from an exported iterm2 (https://iterm2.com/) profile color scheme.

To use it, do something like this (I use yarn and bun, but npm and node should work fine as well):

$ mkdir -p ~/.config/ghostty/themes # not needed if it already exists
$ yarn install
$ bun convertcolors.js samples/Pastels.itermcolors > ~/.config/ghostty/themes/Pastels
