HTML Colors

Colors are very important to give a good look and feel to your website. You can specify colors on page level using <body> tag or you can set colors for individual tags using bgcolor attribute.
The <body> tag has following attributes which can be used to set different colors:

  • bgcolor - sets a color for the background of the page.
  • text - sets a color for the body text.
  • alink - sets a color for active links or selected links.
  • link - sets a color for linked text.
  • vlink - sets a color for visited links - that is, for linked text that you have already clicked on.

HTML Color Coding Methods

There are following three different methods to set colors in your web page:
  • Color names - You can specify color names directly like green, blue or red.
  • Hex codes - A six-digit code representing the amount of red, green, and blue that makes up the color.
  • Color decimal or percentage values - This value is specified using the rgb( ) property.
