In exactly the same way as any other data. If you want to save it
per-product, you could do something like this.
<?php
session_start();
if (empty($_SESSION['products'])) {
$_SESSION['products'] = array();
}
// appropriate checking for form submission here.
// and also making sure proper colors or whatever are posted.
// ....
$session_product = array();
$session_product['product_id'] = $_POST['product_id'];
$session_product['color'] = $_POST['color'];
// add the new array of info to the session.
array_push($_SESSION['products'], $session_product);
now if you print_r($_SESSION['products']) you'll see a big array of info
with each product having a color.
