        // Generate random values for RGB

        Random random = new Random();

        int red = random.nextInt(256);

        int green = random.nextInt(256);

        int blue = random.nextInt(256);


        // Create a new Color object with the random values

        Color randomColor = new Color(red, green, blue);


        // Set the background color of the panel to the random color

        colorPanel.setBackground(randomColor);

    }
