foot has this problem where, if you open a TUI app and then close it,
the terminal color scheme goes back to the preconfigured colors rather
than keep using pywal colors.
This particular problem isn't there in Alacritty, however alacritty does
not support sixel for image previes, so currently using the sixel
patched version of alacritty: https://github.com/ayosec/alacritty
Since we are loading the pywal colors through zsh,
doing `foot -e ncmpcpp` will bypass the interactive shell commands
so instead use `foot -e zsh -i -c ncmpcpp`
This script uses ddcutil and allows you to also control the brightness
of external displays.
It changes the brightness of the display that you are currently focused
in.
