Java SE (Java Platform, Standard Edition)

I'm new to JavaFX and just started my first FX program.  I created an FX project in NetBeans 7.3 and the project runs properly.   All of the samples in the JavaFX samples download run as well.  But when I try to do something as simple as setting the background color on my first scene to black, I can't get it to work.  I find examples and documentation that tell me that what I am doing should work but it does not. 

        Scene scene = new Scene(root, 300, 250, Color.BLACK);

        scene.setFill(Color.BLACK);

        primaryStage.initStyle(StageStyle.UNDECORATED);

        primaryStage.setTitle("Hello World!");

        primaryStage.setScene(scene);

The two bold lines are marked as errors.  Unfortunately, I can't find a way to copy the error popup text in the IDE so I'll summarize.  Both lines are giving errors that say that I gave a Color but a Paint was expected.

Is there something I am missing? Can it be this hard to set a background color in JavaFX?

Thanks.
