title: Why my gnome-terminal cant set colorscheme
body: <p>I can't set up vim colorschemes(<a href="https://github.com/oguzbilgic/sexy-railscasts-theme" rel="nofollow noreferrer">sexy-railscast</a> and others) with 256 colors. How to check where the problem is?</p>
  
  <p>In <a href="https://gist.github.com/1968754" rel="nofollow noreferrer">my vimrc</a> I have <code>:echo has("gui") =&gt; 1</code> but when I added <code>set t_Co=256</code> nothing happens.</p>
  
  <p>Also in <code>.~/.profile</code> I added: <code>export TERM="gnome-256color"</code></p>
