title: Programmatically get theme colors
body: <p>I'm working on an app right now which uses subclassed <code>ImageView</code> to show an image with a bounding box over part of it.</p>
  
  <p>Right now the box is drawn in yellow no matter what, but I think it would look a lot better if the color matched the system's button pressed color, such as orange for the Droid, green for the Evo, or blue for the Galaxy S.</p>
  
  <p>I looked around the APIs a bit, but couldn't find how to programmatically nab that color.
  Any ideas?</p>
