Colors on a Web Page
Colors on a Web page may be inserted in two ways. It may
be inserted either with the name of the color or with
hexadecimal numbers
that represent the RGB (Red-Green-Blue) equivalent. The RGB color value
is used by graphics programs, such as Paint Shop Pro.
The following tags both provide a white background: <body
bgcolor="white"> or <body bgcolor="#ffffff">

RGB (Red, Green, and Blue) Color Codes
Graphics programs use the RGB color value represented by either three
decimal numbers or three hexadecimal numbers. The decimal
numbers used
are 0 through 255 separated by a space. For example, white is 255 255 255
and black is 0 0 0. The hexadecimal number looks like this: white
is ffffff and black is 000000.
Before we can use a color on a Web page for background or font color we
need to convert the decimal RGB value to hexadecimal RGB value.
The hexadecimal number system uses 16 as the base, employing the numbers
0 through 9 and representing digits greater than 9 with the letters A
through F.
To convert the RGB decimal code to hex you can use the scientific
calculator
available in Windows under Accessories.
