Customize colors for __git_ps1 with GIT_PS1_SHOWCOLORHINTS

Question

What I have tried

I have updated my prompt to include the branch name using __git_ps1. In addition, I set GIT_PS1_SHOWCOLORHINTS.

Answer 1

The colours shown by __git_ps1 for dirty branches don't affect the branch name; they affect the "dirty state indicator". In addition to enabling colours, if you enable this indicator you will see a red asterisk for a dirty branch:

old-prompt $ bash --noprofile --norc
bash-4.2$ source /etc/bash_completion.d/git-prompt
bash-4.2$ export GIT_PS1_SHOWCOLORHINTS=1
bash-4.2$ export GIT_PS1_SHOWDIRTYSTATE=1
bash-4.2$ export PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
chris@machine:~/path/to/dir (master *)$

There is no way to change the colour of the branch name based on dirty status without modifying the git-prompt.sh code, or providing your own function.

Note that this works with export PROMPT_COMMAND but not export PS1.
