That should have said "... on the default colors used for the colored
output of..."

The script could query config for these colors, but that would amount to
4 additional forks and "git config" calls each time a prompt is
generated. If you want the colors to be configurable, you should
probably rather introduce environment variables - or edit your copy of
the script ;)
