Cygnus Knight Related Speculation?

Annihiliate is the 4th job shark attack, that animation is for Heaven and Earth.

Anyway, I'm pretty sure the skills, Elemental Harmony and Expert, are just colored based on the elemental system in the game, barring holy and dark, we have fire as red/orange, ice as blue, poison as purple and lightning as yellow/green.

But wouldn't Poison also be green (F/P)? I feel like it matches more to the Cygnus instead of the elements in-game.

It will be conclusive once we see what the next revamp is after WA.
