The Standard Color Map

Within Netscape Navigator and Internet Explorer, you can change the color of various elements of your document, including these elements (partial list; see main text for all occasions).

Element Associated Tag and Attribute
Document background <body bgcolor=color>
All document text <body text=color>
Active hyperlinks <body alink=color>
Visited hyperlinks <body vlink=color>
Regular hyperlinks <body link=color>
Small portion of text <font color=color>
Table cells <table=color>
<tr bgcolor=color>
<td bgcolor=color>
<th bgcolor=color>

Color Values

In all cases, you may specify the color value as a six-digit hexadecimal number that represents the red, green, and blue (RGB) components of the color. The first two digits correspond to the red component of the color, the next two the green component, and the last two the blue component. A value of 00 corresponds to the component being completely off; a value of FF (255) corresponds to the component being completely on. Thus, bright red is FF0000, bright green is 00FF00, and bright blue is 0000FF. Other primary colors are mixtures of two components, such as yellow (FFFF00), magenta (FF00FF), and cyan (00FFFF). White (FFFFFF) and black (000000) are also easy to figure out.

You use these values in a tag by replacing the color with the RGB triple, preceded by a pound sign (#). Thus, to make all visited links display as magenta, use this body tag:

<body vlink="#FF00FF">
