I am struggling to set the accent colour of my application. This is the colour that is used for certain

You can define a style setter property in App.xaml

Then use CustomRenderer for the controls you need to change colors

    protected override void OnElementChanged(ElementChangedEventArgs e)
    {
        base.OnElementChanged(e);
        if (this.Element != null)
        {
            this.Control.Style = Windows.UI.Xaml.Application.Current.Resources["myNewButtonStyle"] as Windows.UI.Xaml.Style;
        }
    }

in a similar way you would be able to use Themed Resource Dictionary key and apply. This code can be used to have native styles on Xamarin's control.
