You can also specify an RGB color as a six digit hexadecimal number preceded by the pound (#) sign. The first two digits indicate the red value, the second two digits indicate the green value, and the last two digits indicate the blue value. The range for each color value is 00 to FF inclusive. For example:
<!-- red background -->
<BODY BGCOLOR="#FF0000"><!-- gray background -->
<BODY BGCOLOR="#333333">
