How do these numbers result in a specific color?

I'm a little confused on how to change the color of my scoreboard. I realize how to change the font color, but the actual color of the rectangle is very confusing to change. Can someone help me? 
 private void makeImage(String title, String prefix, int score)
    {
        GreenfootImage image = new GreenfootImage(WIDTH, HEIGHT);

        image.setColor(new Color(255,255,255, 128));
        image.fillRect(0, 0, WIDTH, HEIGHT);
        image.setColor(new Color(0, 0, 0, 128));
        image.fillRect(5, 5, WIDTH-10, HEIGHT-10);
        Font font = image.getFont();
        font = font.deriveFont(FONT_SIZE);
        image.setFont(font);
        image.setColor(Color.YELLOW);
        image.drawString(title, 90, 100);
        image.drawString(prefix + score, 25, 200);
        setImage(image);
    }

Please pay specific attention to the Fields and Constructors of the Color class.

There are two ways to set colours. One way is what your font colour is using, which is 
image.setColor(Color.YELLOW);
Greenfoot provides several existed colours like Yellow, White, Red, Pink. You can find these colours on Greenfoot Documentation. Another ways is you make a colour. The method is 
  image.setColor(new Color(int a, int b, int c, int d);
or 
  image.setColor(new Color(int a, int b, int c);
int a, int b, int c make up the RGB (red, green, blue) code and int d determines the transparency (0 is transpartent and 1 is opaque Hope this helps
