title: Color gamut in Xcode 8
body: <p>Today I have installed Xcode 8(beta) and exploring Storyboards. Here we can now set background and tintColor for different traits. That's good news.</p>
  
  <p>But here with trait collection(for example any height X any width) there is another selection of <code>gamuts</code></p>
  
  <p>Here is the screenshot<a href="https://i.stack.imgur.com/LN8Um.png" rel="noreferrer"><img src="https://i.stack.imgur.com/LN8Um.png" alt="enter image description here"></a></p>
  
  <p>As I have searched for <code>gamut</code>, I found that it is related with color.
  I have tried with different combination of <code>gamuts</code> but I am unable to see any difference.</p>
  
  <p>The <a href="https://developer.apple.com/library/prerelease/content/samplecode/ColorGamutShowcase/Listings/README_md.html#//apple_ref/doc/uid/TP40017308-README_md-DontLinkElementID_8" rel="noreferrer">documentation</a> is also not helpful. </p>
  
  <p>The question is how the developers get the benefit of this feature?</p>
