This is more of a work horse example than a real technical article.  It's been placed here for your benefit.  The downloadable zip file at the bottom of the page contains the three files necessary for you to simply plug the functions into your page along with a default page to serve as the example of how to use it.   It's extremely easy.  I've also left a couple of functions for generating an array of colors and plugging them into an HTML table.  This sample of 510 colors is pretty "heavy".  You can adjust the color array function to only hold those colors desired (perhaps the JavaScript supported colors...).  The comments for the functions are in the "colorpalette.asp" file.
