Pen Color

Think of the Graphics object as being like a sheet of paper, some colored pens, and some drawing methods. Use the following to change the color of the paper:

setBackground( Color.something )

Use the following method of the Graphics object to change the pen color:

setColor( Color.something )

For example, if gr is a reference to the Graphics object, then this changes the pen color to blue:

gr.setColor( Color.blue );

Several million colors are possible, but for now, use the pre-defined colors:

Color.red     Color.orange     Color.yellow      Color.green
Color.blue    Color.magenta    Color.white       Color.black
Color.gray    Color.darkGray   Color.lightGray   Color.pink
Color.cyan

These are static values from the class Color. (Look at the documentation under Color to see how to set other colors.)
