Changing The MahApps Metro Theme
If you want to change the default colour scheme, just change which colour resource file is loaded.
from Blue:
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />to Red:
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Red.xaml" />You can also change programatically (once you've loaded every colour resource file) using ThemeManager.ChangeTheme().
