Just wanted to add this in here.
Run a tput colors cmd in your terminal.
We are going to enable 256 colors in your terminal because hey, it's 2013!
sudo apt-get install ncurses-term
Then put this:
Into your ~/.bashrc or ~/.bash_profile file.
Then run tput colors again and see the magic happen! (Don't forget to close and restart your terminal for the changes to take effect.)
Happy coloring! You can then use Digits color tables up top to see the beauty!
