# This script changes the color scheme for the following apps:

# - Alacritty in ~/.configs_pointer/alacritty/alacritty.toml
|
|
# - Vim (indirectly, vim calls this script to determine its own colors)
|
|
# - Vimiv in ~/.configs_pointer/vimiv/vimiv.conf
|
|
# - Vifm (indirectly like vim)
|
|
# - Tmux (passive)

# - Bash (passive)

# Warning: Many other files in these configs depend on this script. Do not
