Perfection. Update your code base, lots of changes.

Have you made any progress?

This is easy to use:

new UISettings().GetColorValue(UIColorType.Accent);

But in mobile, the method "GetColorValue" will throw a InvalidCastException.
I think use:

(Color)Application.Current.Resources["SystemAccentColor"];

It's better.
