The following code demonstrates this problem:


public class HelloTextField extends Application {
    private Group content;
    private String sourceBorder = HelloTextField.class.getResource("border.png").toExternalForm();

    @Override
    public void start(Stage stage) throws Exception {
        stage.setScene(new Scene(content = new Group(), 500, 500));
        stage.centerOnScreen();
        stage.show();

        final TextField label = new TextField();
        label.setPromptText("Enter Pithy Pun");

        label.setStyle("-fx-text-fill:green;"
                + "-fx-prompt-text-fill: blue;"
                + "-fx-highlight-fill: yellow;"
                + "-fx-highlight-text-fill: red;"
                );
        content.getChildren().add(label);
    }


    public static void main(String[] args) {
        Application.launch(HelloTextField.class, args);
    }
}
