I know that the MahApps metro theme comes with "themes" (colour sets), but I don't know how to change them from the default settings in my WPF application.
I have followed the beginners tutorial at MahApps.Metro Documentation (including adding the resource libraries at the top of the page), but it makes no mention about changing the theme.
The component/Styles/Colours.xaml file has the comment "from the cosmopolitan theme pack", which may be a helpful clue to someone better versed in WPF design than me.
I'm talking about an app-wide theme change, not an individual control.
