The colors library supports the g`NO_COLOR` standard out of the box.

In case you wish to also enable automatic output of colors based on the
terminal being interactive (TTY), call g`enable_auto_colors` in your
g`src/initialize.sh`. You may run the following command to add this file:

m`$ bashly add hooks`
