This includes colour of the page itself, the letters on the page, and the colours used to highlight links before and after they've been clicked and even while they're being clicked. The 16 basic colours are standard and dependable, though obviously the range is hardly extensive. The The Visibone 216-Color Webmaster's Palette shows you these colours and lets you click on them for details. If you want to be more adventurous, you can use colours of your own choosing by specifying the six-digit hexadecimal code required. This means that pure Green's number is 00FF00 - ie no red, as much green as possible, and no blue.
Examples are steelblue and goldenrod .
Caution It is possible to design web pages which use colour simply and effectively. It is also possible to overdo it and make a page distracting or unreadable, so exercise restraint and good taste. Colour should be used sparingly to enhance the message of the page, rather than becoming a feature in its own right. Remember also that some of those who use your page may suffer from colour vision problems. You can identify the people responsible for the contents and copyright, give a short description which shows up in the search engine results, and specify keywords, both general and speicifc, which you think might help people to find your page.
