I can only speak for myself, but I really have no idea what you are asking for. What do you mean you have to generate unique hexcolors?

Some sample code might be helpful.

Do you mean a random hex value for an RGB color?

This will create a random hex RGB value as a string:

$randomColor = '#' .
sprintf("%02s", dechex(rand(0, 255))) .
sprintf("%02s", dechex(rand(0, 255))) .
sprintf("%02s", dechex(rand(0, 255)));

This is a code I used to generate a random background color and text.

<?php

$r = rand(200,225);
$g = rand(200,225);
$b = rand(200,225);
$background = dechex($r) . dechex($g) . dechex($b);
$text = dechex($r-120) . dechex($g-120) . dechex($b-120);
?>

<?php
echo "<body bgcolor=\"#$background\">";
echo "<font color=\"#$text\">\n";
?>
