Color Names and Hexadecimal Values

Netscape adopted a naming scheme for a palette of 140 colors to make life easier for webmasters. Unfortunately some of these named colors won't look good on older computers because they dither, so you'll have to use a hexidecimal value from the Web Safe palette of 216 colors from http://www.visibone.com/colorlab/. Hexidecimal values for colors are in the form of #RRGGBB where each pair controls the amount of Red, Green, and Blue in the color. Each component amount can be from 00 - FF (Each digit in a hexadecimal number goes from 0 to 9 and then from A to F), and the entire value is prefixed by a # to indicate it is hexadecimal. ColorLab also has information about designing pages which are accessible to the color blind.
