Now, I want to make the background color of my applet to be transparent with the background color of my HTML file. That means if the background color of my applet is blue while that of my HTML is red. I want there is on blue rectangular seen on web page. How can I do this? Of course, I can select the same color, but I want to have another alternative due to some reasons.

To the best of my knowledge tranparency was only introduced at JDK 1.1 and even than only when you inherit from Component or Container, since Applet is derived from Panel (AFAIR) you cannot get tranparency from an Applet.

Do you mean that the background color of the Web page should impose the background
color of the applet or that the background color of the applet should impose the background
color of the HTML?

Use the same background as the browser (if it is the inverse that you wanted, please tell
me).

In the applet tag, add a parameter:

PARAM NAME="bgColor" VALUE="B8B5AE"
(where VALUE is the same hexadecimal value as the HTML color value)

// in the JAVA init method :
Color bgcolor = new Color(Integer.valueOf(getParameter("bgColor"), 16).intValue());
setBackground(bgcolor);
