The author writes "I used to face some difficulty in choosing background or foreground colors for my applications as the colors provided in java.awt.Color are too few. In the beginning I used to randomly select three integers for the constructor of Color class, apply it, and then see the effect. If not satisfied, then the integers had to be changed, the code compiled and run again to see the effect. After numerous trials I was able to get a color of my choice. To make things easier this applet was written. Of course, if one is using javax.swing package this applet is not required as a class for this very purpose is provided. But for awt buffs this applet would be of some help. Recently, I have also added the functionality of trying out different fonts too."
