Web page colors can be specified by hexadecimal RGB (red-green-blue)
intensity value or simply by name. While the hex method allows for
very accurate specification, the name method is more readable.
Most Web browsers recognize the 136 named colors that are listed in the
following table. The table includes a sample of the color, the color
name, and the matching hexadecimal RGB value. If you don't see any colors
in the first column, then your browser does not support background color
in table cells.
Strangely, most of these colors are not in
Netscape's 216 color non-dithering palette. As
always, it is a good idea to test your Web pages on multiple browser
platforms to determine if the colors look the way you want them to.
