HTML Colors

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.

Now we will see these coloring schemes one by one.

HTML Colors - Hex Codes
A hexadecimal is a 6 digit representation of a color. The first two digits(RR) represent a red value, the next two are a green value(GG), and the last are the blue value(BB).

A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Paintshop Pro or MS Paint.

Each hexadecimal code will be preceded by a pound or hash sign #. Following is a list of few colors using hexadecimal notation.
