If your Api version is Level 21 or above (Android 5.0 and above).You could use SetNavigationBarColor method to set the background color.

protected override void OnCreate(Bundle savedInstanceState)
    {
        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;

        if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
        {
            Window.SetNavigationBarColor(Android.Graphics.Color.Red);
        }

        base.OnCreate(savedInstanceState);
         
        ...
   }
