Answer 1

Assign a SolidColorBrush key in your resource dictionary.

<SolidColorBrush x:Key="DynamicBrush" Color="White"/>

Initially give the color as what you need and bind it to controls in all pages. When user tends to change the color then you can change the key value in your resource dictionary which will be reflected in pages where all you have used that key.

XAML

<Button Content="change" x:Name="BtnChange" Click="BtnChange_Click"/>

C#

private void BtnChange_Click(object sender, RoutedEventArgs e)
    {
        App.Current.Resources["DynamicBrush"] = new SolidColorBrush(Colors.Red);
        this.Foreground = App.Current.Resources["DynamicBrush"] as SolidColorBrush;
    }

This will help you.
