title: White color overlay on CCSprite
body: <p>I'd like to apply some kind of "color overlay" over a CCSprite of mine. Basically, tint it completely white.</p>
  
  <p>I can use</p>
  
  <pre><code>mySprite.color = ccc3(0,0,0);
  </code></pre>
  
  <p>And my sprite gets a black color overlay. However,</p>
  
  <pre><code>mySprite.color = ccc3(255,255,255);
  </code></pre>
  
  <p>Will, naturally, not affect my sprite. Instead, my sprite keeps its original color.</p>
  
  <p>So, is there another method to achieve such? I really can't afford to make a white version of all my animations/sprites etc.</p>
