title: How to change the foreground color of all command buttons in MahApps
body: <p>Is there a way to change buttons foreground in MetroWindow?
  I have even tried to override the IronicallyNamedChromelessButtonStyle but the foreground color was still the same.</p>
  
  <p>Edit:
  The buttons are in the Window Bar (e.g Close, Minimize, Maximize).</p>
