If you know bit of HTML and when you're developing a webpage, I think you would have felt uneasy while choosing the colors for the web. I've developed a small Swing component which will just list down all the known color as shown below in the screenshot. I hope this tool enables you to choose the perfect colors. You need to have two files, one is Java program and other is Properties file which has the color codes used in my program.

Place properties file under the same folder where you've placed the ColorsDemo.java. Compile the code and run it, you'll see the output as a swing window. This program has been tested on 1.5, 1.6, and 1.7 versions of Sun Java.
If you've sometime, why don't you checkout my other Java programs
