How to set colors in OS X (Mavericks) terminal?

Question

I want to set the color's palette of my terminal in order to use properly the Solarized colorscheme for Vim (http://ethanschoonover.com/solarized). I understand that i've to modify my .bash_profile but how? (I also installed https://github.com/amix/vimrc which provide some very cool stuff for Vim)

Solution

Use either of the two scripts from this repository or adjust Terminal.app's default colors manually.
