+       *
+       * iOS Safari (tested on iOS 8.1) does not handle animation-delay very well - it doesn't
+       * guarantee that the animation will start _exactly_ after that value. So we avoid using
+       * animation-delay and instead set custom keyframes for each color (as layer-2undant as it
+       * seems).
+       *
+       * We write out each animation in full (instead of separating animation-name,
+       * animation-duration, etc.) because under the polyfill, Safari does not recognize those
+       * specific properties properly, treats them as -webkit-animation, and overrides the
+       * other animation rules. See https://github.com/Polymer/platform/issues/53.
