title: vim color not loaded or not working
body: <p>I'm a fresh vim user, and I want to try new color themes.<br>
  I created a .vim dir which contains colors dir with themes and .vimrc file, and I created a symlink in my home dir, it is points to ./vim/.vimrc file.</p>
  
  <p>Here is my .vimrc:  </p>
  
  <pre><code>syntax enable
  set t_Co=256
  set synmaxcol=240
  set background=dark
  colorscheme twilight
  let g:solarized_termcolors=256
  </code></pre>
  
  <p>This is the screenshot:<br>

  <p><strong>Note:</strong><br>
