title: How to detect when changes are made to the Windows Color and Appearance settings dialog?
body: <p>I am trying to get my Application to detect when the Windows Themes change, and then be able to respond to that change.</p>
  
  <p>To detect when themes change there is the handy <code>WM_THEMECHANGED</code> message which I am able to respond to.</p>
  
  <p>What I would like is to also be able to determine when color settings change from here:</p>

  <p>I have been searching and looking for any possible way to detect changes made from that dialog but I have yet to find any information for it.</p>
  
  <p>So I would like to know whether it is possible or not to detect changes from the Window Color and Appearance dialog. I understand changes here are not the same as theme changes, but all the same I would like to be able to detect and respond to these changes as well.</p>
