title: Vim CursorLine color change in insert mode
body: <p>There is good snippet for changing cursor color:</p>
  
  <pre><code>if &amp;term =~ "xterm\\|rxvt"
    " use an orange cursor in insert mode
    let &amp;t_SI = "\&lt;Esc&gt;]12;orange\x7"
    " use a red cursor otherwise
    let &amp;t_EI = "\&lt;Esc&gt;]12;red\x7"
    silent !echo -ne "\033]12;red\007"
    " reset cursor when vim exits
    autocmd VimLeave * silent !echo -ne "\033]112\007"
    " use \003]12;gray\007 for gnome-terminal
  endif
  </code></pre>
  
  <p>How should I alter this that instead of cursor, CursorLine would change color for example from dark blue to blue?</p>
