One small thing not mentioned on this page is that iTerm2 v3 now supports 24bit colour.
If you're on the latest vim (install with: brew install --HEAD vim) you can use the same colour schemes designed for gVim in your terminal with :set guicolors

set termguicolorsFor reference I've got vim-7.4.1795 installed. Version string looks like this:
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled May 6 2016 11:18:41)
Edit: Also, just remembered you might need to run brew update before brew install to get the latest installation formula.
if has('termguicolors') && !has('gui_running')
set termguicolors
