Suppose you are doing a lot of Web design, and you want to look at
different colors to add to your pages. Web browsers let you specify the

browsers, you need to know the RGB values, or even the hexadecimal
value, of a color. Suppose you want an http://www.greateventsupport.com
applet that enables users to see how
a certain RGB color appears inside their Web browser. It would make
