title: Use Same Variable In Multiple View Controllers
body: <p>I have two colour variables:</p>
  
  <pre><code>var blue = UIColor(red:0.08, green:0.49, blue:0.49, alpha:1.0)
  var red = UIColor(red:0.61, green:0.12, blue:0.20, alpha:1.0)
  </code></pre>
  
  <p>I have declared these variables in my <code>EntryViewController</code>, however, I also need to use them in my other <code>ViewControllers</code>. I was wondering if it were possible to use the same variables in multiple <code>ViewControllers</code>? I already know about passing data with segues, but I was wondering if there were a way to maybe declare the colours in their own class and subclass my <code>ViewControllers</code> with this class. Thank you.</p>
