title: Get the active color of Windows 8 automatic color theme
body: <p>In Windows 8, I have set the color scheme to automatic and configured my wallpaper to change after x minutes. The color scheme changes according to the active wallpaper. </p>
  
  <p>I'm developing a WPF application and would like to have my gradients change when Windows changes the color scheme to match the current wallpaper.</p>
  
  <p>Is there a way get the current/actual color scheme and be notified of the change in C#?</p>
