Unless you're doing something special here (I'm not too sure what you mean by 'may not cover the background image'), I don't think you need an 'effect'.
Try this:
private Rectangle createSelectWindow(final Color color, double length) {
        Rectangle rect = new Rectangle(length, length);
        rect.setFill(Color.RED);
        rect.setStroke(Color.RED);
        rect.setOpacity(0.5);  // i.e. make it 50% visible
        rect.setCursor(Cursor.HAND);
        return rect;
}Or, if you don't want the border to be translucent and just the fill, try this:
private Rectangle createSelectWindow(final Color color, double length) {
        Rectangle rect = new Rectangle(length, length);
        rect.setFill(new Color(1, 0, 0, 0.5));  // rgba - use an alpha of 0.5 on the fill color
        rect.setStroke(Color.RED);
        rect.setCursor(Cursor.HAND);
        rootPane.getChildren().add(rect);
}
