So for everyone wondering about this lens color it apparently does not exist.
I just got off the phone with CS due to the order showing "call customer care". I talked to the rep who actually seemed fairly knowledgable. She explained that IT had entered some code incorrectly and that the lens color was supposed to be listed as transitions rather than Prizm. This had apparently happened on some frogskins recently as well. So no Prizm black clear..lol.
