I don't like the purple glow either. It makes me feel evil.

I would have expected to see:

WAR - red
PLD - silver
WHM - green/red intertwined
BLM - purple/black intertwined
MNK - gold
BRD - blue/magenta intertwined
SCH - green/purple intertwined
DRG - black?

you know, same sort of color as the AF color schemes.
