Here is a way to get a random background color for your website.
printf is needed to generate a valid color code,
because zero padding is needed (4 has to become 04)
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<?php
function getRandomColor()
{
$_ROOD = dechex(rand(0,255));
$_GROEN= dechex(rand(0,255));
$_BLAUW= dechex(rand(0,255));
printf('%02s',$_ROOD);
printf('%02s',$_GROEN);
printf('%02s',$_BLAUW);
}
?>
<BODY BGCOLOR="#<?php getRandomColor();?>" TEXT="#000000"
LINK="#FF0000"
VLINK="#800000" ALINK="#FF00FF" BACKGROUND="?">
</BODY>
</HTML>
