Here is a short bit of code to generate a random hexadecimal colour using PHP. Essentially you just create a random number between 0 (000000) and 10,000,000 (ffffff) and turn this into a hexadecimal number using the PHP function dechex.

$colour = rand(0,10000000);
$colour = dechex($colour);

This can be accomplished on a single line.

$colour = dechex(rand(0,10000000));
