如何在Xamarin.forms中使用颜色的可绑定属性？

public static readonly BindableProperty ColorProperty = BindableProperty.Create(
    "Color", typeof(Color), typeof(MyControl), Color.Default);

public Color Color
{
    get { return (Color)GetValue(ColorProperty); }
    set { SetValue(ColorProperty, value); }
}

<Label Text="Hello, Xamarin.Forms!" TextColor="{Binding MyColor}" />

private Color myColor;
public Color MyColor
{
    get { return myColor; }
    set
    {
        myColor = value;
        OnPropertyChanged(nameof(MyColor));
    }
}
