Which background color is active in Windows Phone 7?

Question

How do I know whether WP7 is in its dark mode or light mode? I would like to show different images depending on which mode is active.

Answer 1

  Visibility v = (Visibility)Resources["PhoneLightThemeVisibility"];

  if (v == System.Windows.Visibility.Visible)
  {
     // light theme is active
  }
  else
  {
    // dark theme is active
  }
