Okay so, the Padjali weapons retain their aetheric forms of light, and glow the same color as the soul crystal for each job, most anyway:

Paladin: Pale Blue
Monk: Yellow
Warrior: Red
Dragoon: Blue (slightly lighter than Scholar)
Bard: Chartreuse
Ninja: Dark Purple
Dark Knight: Burgundy
Machinist: Cyan
White Mage: White/Ecru
Black Mage: Purple
Summoner: Green
Scholar: Blue (slightly darker than Dragoon)
Astrologian: Orange

But, can you figure out which silhouette matches each weapon. The only one I am really sure of is the DRK weapon, it has to be Balmung, since I use the actual sword as my glamour, lol. Okay so lets see if we can guess them all.
