Trivia

 * Despite the note of uncertainty in Paths of Destiny, potions do not tend to deviate from the expected abilities by color in Ultima V. Perhaps this says more about the capabilities of Sir Adam, who seems to cause much destruction with his experimentation, than about other potion manufacturers at the time.
 * According to The Apothecary's Desk Reference, white potions previously allowed for X-Ray vision, but were outlawed after an infamous peeping-tom case.
 * Pouring a potion to the floor in Ultima VII, the companions will scold the Avatar for wasting it. Also, using a potion that's not yours is one of the best ways to tick off people (including companions).
