title: Android Studio IDE color scheme settings cannot revoke to default white background
body: <p>I just installed the latest Android Studio beta 0.8.
  Played with the Settings -> Editor -> Colors &amp; Fonts , changed Scheme name: from Default to 'Darcula'. So the background colour was changed to dard grey.
  I don't feel comfortable with that and I changed back to Default.</p>
  
  <p>Only the Editor area background revoked back to white, all other area such as Project explorer, Properties are still dark grey.</p>
  
  <p>Anyway I can reset to original white background?</p>
  
  <p>Thanks</p>
