title: What's the difference between displayP3Red and red
body: <p>In Swift I have found two ways to initialize an UIColor</p>
  
  <pre><code>UIColor(displayP3Red: CGFloat, green: CGFloat, blue: CGFloat, alpha: CGFloat)
  UIColor(red: CGFloat, green: CGFloat, blue: CGFloat, alpha: CGFloat)
  </code></pre>
  
  <p>Is there a difference between those two ways?</p>
