title: Where should I store 30+ UIColors for quick reference?
body: <p>I want to have 30+ constant UIColors so I can easily access them in my app.  I'd like to be able to do something like this:</p>
  
  <pre><code> [self setBackgroundColor:[UIColor skyColor]];
   [self setBackgroundColor:[UIColor dirtColor]];
   [self setBackgroundColor:[UIColor yankeesColor]];
  </code></pre>
  
  <p>How can I do this?</p>
  
  <p>Thanks!!</p>
