The following chart is one of the many guides that are available on the Internet for colour codes to use on your web page. These colours are for the more basic monitors that only give you 16 or 256 colours. If you have a monitor and card that give you colours in the millions, then there is another chart that you will find more usefull. Unfortunately, I didn't save the address of that chart so am in the process of trying to find it again.
When I do, I will include it here on this page.
