Then source them in your `~/.mutt/muttrc`, e.g.
- source ~/.mutt/colors-gruvbox-shuber.muttrc
+ source ~/.mutt/gruvbox/colors-gruvbox-shuber.muttrc
# For neomutt also add this line:
- # source ~/.mutt/colors-gruvbox-shuber-extended.muttrc
+ # source ~/.mutt/gruvbox/colors-gruvbox-shuber-extended.muttrc
The colorscheme is split into two files, where the latter also defines colors
for neomutt.
