A hexadecimal color is specified with: #RRGGBB, where the RR (red), GG (green) and BB (blue) hexadecimal integers specify the components of the color.
The most common way of coloring HTML text is by using hexadecimal color codes (Hex code for short). Simply add a style attribute to the text element you want to color – a paragraph in the example below – and use the color property with your Hex code.
Example:
HTML
<!DOCTYPE html>
<html>
<body>
<p style="color:#FF0000";>Red paragraph text</p>
</body>
</html>
Example:
HTML
<!DOCTYPE html>
<html>
<body>
<p style="color:red;">Red paragraph text</p>
</body>
</html>
In HTML, a color can be specified using a hexadecimal value in the form:
#rrggbb
Where rr (red), gg (green) and bb (blue) are hexadecimal values between 00 and ff (same as decimal 0-255).
For example, #ff0000 is displayed as red, because red is set to its highest value (ff), and the other two (green and blue) are set to 00.
Another example, #00ff00 is displayed as green, because green is set to its highest value (ff), and the other two (red and blue) are set to 00.
To display black, set all color parameters to 00, like this: #000000.
To display white, set all color parameters to ff, like this: #ffffff.
Example:
HTML
<!DOCTYPE html>
<html>
<body>
<h1 style="background-color:#ff0000;">#ff0000</h1>
<h1 style="background-color:#0000ff;">#0000ff</h1>
<h1 style="background-color:#3cb371;">#3cb371</h1>
<h1 style="background-color:#ee82ee;">#ee82ee</h1>
<h1 style="background-color:#ffa500;">#ffa500</h1>
<h1 style="background-color:#6a5acd;">#6a5acd</h1>
</body>
</html>
Shades of gray are often defined using equal values for all three parameters:
Example:
HTML
<!DOCTYPE html>
<html>
<body>
<h1 style="background-color:#404040;">#404040</h1>
<h1 style="background-color:#686868;">#686868</h1>
<h1 style="background-color:#a0a0a0;">#a0a0a0</h1>
<h1 style="background-color:#bebebe;">#bebebe</h1>
<h1 style="background-color:#dcdcdc;">#dcdcdc</h1>
<h1 style="background-color:#f8f8f8;">#f8f8f8</h1>
</body>
