When color values are called for in any HTML tag, they may be specified either by name or + by color value. The following named colors are supported:
+| Black |
+ Maroon |
+ Gray |
+ Red |
+
| Navy |
+ Purple |
+ Blue |
+ Fuchsia |
+
| Green |
+ Olive |
+ Lime |
+ Yellow |
+
| Teal |
+ Silver |
+ Aqua |
+ White |
+
Colors may also be specified as a color value in the form "#RRGGBB", where RR, + GG, and BB represent color intensity values for red, green, and blue, + respectively, as hexadecimal values from 00 to FF (decimal 0 to 255). For example, the color + "red" in the table above may also be represented as "#FF0000". In this color example, red + is set to its highest possible value (hex FF, decimal 255), while green and blue are set to 0.
+Although red-green-blue color values theoretically allow for many thousands of colors, + the actual number of colors available depends on the color capabilities of the devices the + document will be viewed on. Many personal computers can display only 16 colors due to the + type of video display adapter they use.
In HTML, certain special characters may be written as &name;, where + name is a symbolic name. The most important of these are < (the less-than + sign, or <), > (the greater-than sign, or >), and & (the ampersand + itself, or &). These allow you to use characters normally used by HTML to indicate + formatting commands.
+In addition, special characters may be written as &#nnn;, where nnn + is a decimal character code in the document's character set (usually the ISO Latin-1 character + set).
+Here follows a listing of additional special characters in HTML. (NOTE: + Your browser may not display all of these properly.)
