<?php

$color = "#cc3366";
$tint = 0.10; // =10%
echo get_tint($color, $tint); // "#faebf0"

function get_tint($c,$t)
{
$r = hexdec(substr($c,1,2));
$g = hexdec(substr($c,3,2));
$b = hexdec(substr($c,5,2));

$rt = "0" . dechex(round($t * $r + (1-$t) * 255));
$gt = "0" . dechex(round($t * $g + (1-$t) * 255));
$bt = "0" . dechex(round($t * $b + (1-$t) * 255));

$tint = "#" . substr($rt,-2) . substr($gt,-2) . substr($bt,-2);

return $tint;
}
