title: How to install emacs colortheme
body: <p>I found <a href="http://www.emacswiki.org/emacs/ColorTheme">this website</a> and downloaded the color-theme files.
  It says:</p>
  
  <blockquote>
    <p>Put the file color-theme.el and the
    folder “themes” (with the files
    color-theme-example.el and
    color-theme-library.el) in a directory
    on your LoadPath.</p>
  </blockquote>
  
  <p>and then I checked <a href="http://www.emacswiki.org/emacs/LoadPath">the load path website</a>, which says:</p>
  
  <blockquote>
    <p>To add a single directory to the load-path:</p>
  </blockquote>
  
  <pre><code>(add-to-list 'load-path "~/.emacs.d/site-lisp/")
  </code></pre>
  
  <p>My question is, where do I type this line?
  If I do <code>M-x</code> and then type, it complains <code>add-to-list[No match]</code>.</p>
  
  <p>By the way, I am using Emacs 23.2(9.0) on Mac, a GUI version.
  For the text version on terminal, I use black background seems fine, except the blue is too dark on black</p>
