How to make a color darker in Java

Question

I am making a drawing tool in java, but the orange is seems a bit too light. Where to put the color name at the function public Color darker()?

      public void clear() {
        g2.setPaint(Color.white);
        // draw white on entire draw area to clear
        g2.fillRect(0, 0, getSize().width, getSize().height);
        g2.setPaint(Color.black);
        repaint();
      }

      public void red() {
        // apply red color on g2 context
        g2.setPaint(Color.red);
      }

      public void black() {
        g2.setPaint(Color.black);
      }

      public void magenta() {
        g2.setPaint(Color.magenta);
      }

      public void green() {
        g2.setPaint(Color.green);
      }

      public void blue() {
        g2.setPaint(Color.blue);
      }
      public void yellow() {
        g2.setPaint(Color.yellow);
      }
      public void orange() {
        g2.setPaint(Color.orange.darker);
      }
    }

Please tell me what to write to make the orange darker.

Solution

You can do:

Color.ORANGE.darker()

or

Color.orange.darker()

Also, if you still think that it is not dark enough, you can even do:

Color.orange.darker().darker().darker().darker().darker() // as many times as you want!

Also, the default orange color, as defined in the class is:

new Color(255, 200, 0)

If you want, you may do something with those numbers!

In your code, change this line:

g2.setPaint(Color.orange.darker);

to

g2.setPaint(Color.orange.darker()); // darker ain't a var, it is a method.

And,

drawArea.orange.darker();

to

 drawArea.orange(); //You cannot call darker() on void!
