How do I use the correct Windows system colors?

Question

I want to use XAML to style a WPF button to look like the "Mixer" and "Change date and time settings..." text of these Windows 7 Notification area flyouts.

Does a property of SystemColors define that color? Which?

<Setter Property="Foreground"
        Value="{DynamicResource {x:Static SystemColors.????}}" />

Answer 1

The best method I've found is experimentation and guessing.

I created a little utility to visualize these colors.
