> To add more color to your Git output: git config --global color.ui 1
Don't do this. The default (since 1.8.4) is auto, which adds colors if the output goes to a terminal, but doesn't if the output goes somewhere else (e.g., a pipe). That is probably what you want (and already have).
I fell for this myself at some point. Somehow expecting there to be more colors, or full color support, or something like that — Nope.
Better yet, if you just want to get to work and have a sexy terminal, use https://github.com/mathiasbynens/dotfiles
To install on Mac just run:
git clone https://github.com/mathiasbynens/dotfiles.git && cd dotfiles && source bootstrap.sh
