Setting colors for prompt in Git Bash on Windows
In your .bashrc you can set your prompt using the PS1 variable (which is likely set to a global value in /etc/profile or another file in /etc which may be distribution dependent).
Here's an example:
PS1='\[\033[1;36m\]\u@\h:\[\033[0m\]\[\033[1;34m\]\w\[\033[0m\] \[\033[1;32m\]$(__git_ps1)\[\033[0m\]\$ 'In order for the command substitution to work, you need shopt -s promptvars which is the default.
This will output the user and hostname in cyan, the current directory in blue and the git branch in green on terminals that work with TERM=xterm-color.
See man 5 terminfo and man tput for more information about terminal controls.
