The answer is, I'm sure, neither C1 or C3, but Panerai's in-house mix of lume colors. It has been reported that 1 part C3 to 2 parts C1 is a close match.
I'm sure the gen has the hands are lumed with the same mix as the dials. The only option is to have the lume re-done.
Talk to vaccum or Flav.
Good luck!
