How to tell if the user has selected a Light or Dark theme

Question

Is there a way to tell if the user has selected a Light or Dark theme?

Thanks!

There is a property to test for this, rather that comparing the actual resource color.

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

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