  <p>I'd like to use few colours throughout my app. Instead of creating a UIColor at every instance or in every viewController is there a way by which i can use it throughout the app.</p>
  
  <p>or is it wise to use a ColourConstants.h header file where i #define each colour i want to use</p>
  
  <p>i.e </p>
  
  <pre><code>#define SCARLET [UIColor colorWithRed:207.0/255.0 green:47.0/255.0 blue:40.0/255.0 alpha:1];
  </code></pre>
  
  <p>thanks in advance!</p>
