title: UITabBarItem selectedImageTintColor. How to find the color to set as tintcolor
body: <p>I was using the <code>selectedImageTintColor</code> property in my <code>TabBarController</code> to change the color of the selected <code>TabBarItem</code>.</p>
  
  <p>The problem is that the color you set as <code>tintcolor</code> is not the final color applied, before it is changed (it gets some kind of gradient)</p>
  
  <p>My question is, is it possible to find the color to apply as <code>tintcolor</code> to obtain a final color you know?</p>
  
  <p>For example, I want my selected item to have a final color of </p>
  
  <pre><code>[UIColor colorWithRed:(154.0/255.0) green:(213.0/255.0) blue:(0.0) alpha:(1.0)
  </code></pre>
  
  <p>What are the color RGBs I should set to the property <code>selectedImageTintColor</code>?</p>
