title: Change color of text when button is pushed?
body: <p>I know how to change the background color but what about the actual text? There doesn't seem to be a member on a UIButton called "color" or anything like that. 
  My code:</p>
  
  <pre><code>@IBAction func yellowBtnClicked(sender: UIButton) {
          gameboard.image = UIImage(named: "Yellow_gb")
          resultsView.image = UIImage(named: "Yellow_results")
          colorsView.image = UIImage(named: "Yellow_colors")
          colorsBtn.color = UIColor.brownColor() //This line has the issue
  
      }
  </code></pre>
