//Start of colorful tag cloud
function colorCloud($text) {
 $text = preg_replace_callback('|<a (.+?)>|i', 'colorCloudCallback', $text);
 return $text;
}
function colorCloudCallback($matches) {
 $text = $matches[1];
 $color = dechex(rand(0,16777215));
 $pattern = '/style=(\'|\")(.*)(\'|\")/i';
 $text = preg_replace($pattern, "style=\"color:#{$color};$2;\"", $text);
 return "<a $text>";
}
add_filter('wp_tag_cloud', 'colorCloud', 1);
//End of colorful tag cloud

Add the subjacent code to where you want the tag cloud show. And it’s done, you can see the colorful tag cloud in your wordpress blog now.
