title: Changing Color/Alpha/Filter to MKMapView iOS 6
body: <p>Is there a way to apply CI Filters to <code>MKMapViews</code>? Or something similar? I'm trying to not have my map based app looks so beige. Is there way to apply <code>RGBA</code> filters?</p>
  
  <p>Any help/tutorials direction appreciated. I see nothing in the native documentation that talks about changing look for <code>MKMapView</code>.</p>
