title: How to replicate PS multiply layer mode
body: <p>Does anybody know of a good way to replicate Photoshop's multiply layer mode using either an image or CSS?</p>
  
  <p>I'm working on a project that has thumbnails that get a color overlay when you hover over them, but the designer used a layer set to multiply and I can't figure out how to produce it on the web.</p>
  
  <p>The best thing I've come up with is either using rgba or a transparent png, but even then it doesn't look right.</p>
