Well, I feel silly. I had KD but changed it to Phi Mu.
KD's pledge pin has green on it.
If we're going to go w/ emeralds being the green on the badge, according to ariesrising's site, both Kappa Delta and Phi Mu badges can have emeralds on them.
I just don't know if Phi Mu badges can come in silver (according to kddani, KD's can).
