title: How to set background color of layer in cocos2d-x?
body: <p>I've been writing a game using cocos2d-x and ran into an issue with changing the background color. I found an <a href="http://www.raywenderlich.com/352/how-to-make-a-simple-iphone-game-with-cocos2d-tutorial" rel="noreferrer">example</a> in cocos2d, but apparently this only applies to cocos2d which is written in Obj-c. Basically the idea is to use a CCLayerColor instead of CCLayer, and when the constructor gets fired set the color.</p>
  
  <p>Does anyone know how to change the background color in cocos2d-x? Seems like it would be pretty simple, I'm pretty sure I'm missing something obvious.</p>
