Trying to see ItemMeta of Clicked Item while Stripping Color

Hmmm, I don't think I'm doing this right.
Currently, I'm trying to make a simple GUI.
I'm checking to see if the item they clicked, is a certain item. If it is, then I would do the giveMageKit() or the giveWarriorKit() methods. I'm getting a ton of errors when I click them, and the if statements are simply not working. Any alternatives?

Code (Text):

@EventHandler
    public void onInventoryClick(InventoryClickEvent e) {

        Player player = (Player) e.getWhoClicked();

        if (!e.getInventory().getName().equals("Classes"))
            return;

        if (e.getCurrentItem().getItemMeta().getDisplayName().equals(ChatColor.stripColor("Mage"))) {
            giveMageKit(player);
            e.setCancelled(true);
        }
        if (e.getCurrentItem().getItemMeta().getDisplayName().equals(ChatColor.stripColor("Warrior"))) {
            giveWarriorKit(player);
            e.setCancelled(true);

        }

    }
 

 

Here is the error:
