title: Alpha transparent PNGs not displaying correctly in Mobile Safari
body: <p>I'm using some semi-transparent PNGs as background-images on various websites. These are usually something like a 1x1 image with a 30-percent opaque white layer.</p>
  
  <p>I've noticed that Mobile Safari does not display them correctly, giving them a darker/grayish tint.</p>
  
  <p>Is this a MobileSafari bug (I couldn't imagine so), or do I need to do something different, either to my pages or PNGs?</p>
  
  <p>(Here's how I create the PNGs:  In Photoshop, create a 1x1 transparent canvas. Draw a white rectangle in Layer 1. Set opacity to, say 30 percent, Save for Web as 24-bit PNG with transparency.)</p>
