Blue

You decide to sample the blue potion as the three goblins watch with intense curiosity. It tastes a little metallic and sour, and not unlike certain kinds of booze.

You wait for a while for anything to happen, not feeling very different, until you look down at your hand and notice tiny stripes appearing on your skin and expanding. Slowly you skin changes to blue, and you stare into a mirror in shock as your lips become purple and hair turns gold. Immediately after, you are covered in cold blue magical fire and it burns off all of your clothes.
