title: XCode iOS colors do not match after building
body: <p>My UIView and UIImageView colors look perfect in interface builder, but are perverted upon building - see the pic below with IB on the left, and the simulator on the right:</p>
  
  <p><img src="https://i.stack.imgur.com/1fASm.png" alt="On the left: Interface Builder, On the right: iOS Simulator"></p>
  
  <p>There is a UIView with it's background color manually set to 65, 126, 218 - and on top of that a UIImageView for the "checkout" text, and a UIButton with it's Image set for the settings gear.  Assets are PNG.</p>
  
  <p>The asset colors read correctly, and everything appears to line up just right in interface builder as I can't see any seams.  However, when I build the background color on the view changes slightly, and the asset colors change as well.  Using the color-picker shows that both colors have been perverted somewhere in the process.</p>
  
  <p>How do I get my colors to remain true between IB and building?</p>
