How about this?
* The color scheme of the default header buttons is automatically adjusted to
remain easily recognizable
* by inspecting the {@link Scene#fillProperty() Scene.fill} property to gauge
the brightness of the user
* interface. Applications should set the scene fill to a color that matches the
user interface of the header
* bar area, even if the scene fill is not visible because it is obscured by
other controls.
