Incorrect colors with vim in iTerm2 using Solarized

Question

I am having a strange issue with iTerm2, in terminal vim (non-gui) and the solarized color scheme. First, I have set iTerm2 to use the dark solarized colour scheme.

Answer 1

I tried all of the previous suggestions. I just added set t_Co=256 to .vimrc and it was fixed. I didn't need to create a tmux alias or change my config file.
