title: How to initialize UIColor with white color
body: <p>I am trying to initialize <code>UIColor</code> instance with <code>whiteColor</code> and I am not able to do it. The screen appears black if I do this:</p>
  
  <pre><code>color = [UIColor colorWithWhite:1.0 alpha:1.0];
  </code></pre>
  
  <p>But below line works fine ...</p>
  
  <pre><code>color = [UIColor colorWithRed:197.0/255.0 
                          green:169.0/255.0 
                           blue:140.0/255.0 
                          alpha:1.0];
  </code></pre>
  
  <p>I am sure I am doing something stupid, any ideas?</p>
