Introduction: 

 A Color in HTML is defined by it's Red, Green and Blue Value. 
The HTML backgound color is defined with: 
<body bgcolor=#xxyyzz> 

  • xx = Red Color Value: 00-FF
  • yy = Green Color Value: 00-FF
  • zz = Blue Color Value: 00-FF
Examples:
  1. <body bgcolor=#FF0000> produces a red background color.
  2. <body bgcolor=#00FF00> produces a green background color.
  3. <body bgcolor=#FFFFFF> produces a white background color.
It's also possible to define a text color with:
<body bgcolor=#xxyyzz text=#xxyyzz>

Examples:

  1. <body bgcolor=#FFFFFF text=#FF0000>

  2. produces a white background color with red text.
