title: UIToolbar setBackgroundColor doesn't fully change color
body: <p>I'm trying to set the background color of a <code>UIToolBar</code>.
  I tried selecting the color from IB's Attribute Inspector, and tried setting it programmatically through <code>setBackgroundColor:[UIColor ...]</code>.</p>
  
  <p>Both solutions work, but only partially: the color blends something like 50% with white and the toolbar is very light...doesn't show the color I actually chose, but a much lighter version of it.</p>
  
  <p>How can I have the <code>UIToolBar</code> of the actual color I'm choosing?
  It's probably very simple to solve, but I can't find a way and can't find answers online either.</p>
