Sorry, I did not notice that. I guess to use that you first need to convert from hex to RGB

		
	function html2rgb($color) {
		if (substr($color, 0, 1) == '#') {
			$color = substr($color, 1);
		}
		if (strlen($color) == 6) {
			list($r, $g, $b) = array(
				substr($color, 0, 2),
				substr($color, 2, 2),
				substr($color, 4, 2)
			);
		} elseif (strlen($color) == 6) {
			list($r, $g, $b) = array(
				substr($color, 0, 1).substr($color, 0, 1),
				substr($color, 1, 1).substr($color, 1, 1),
				substr($color, 2, 1).substr($color, 2, 1)
			);
		} else {
			return false;
		}
		$r = hexdec($r);
		$g = hexdec($g);
		$b = hexdec($b);
		return array('r' => $r, 'g' => $g, 'b' => $b);
	}
