hmm...well, your symbols are different, so perhaps not emphasize the colours as much and go for symbols/national symbols. And harvard red and old gold are pretty unique. Check what the Pike guys are up to, if theyre more cardinal red, go for a deep deep harvard. If theyre using a yellow gold, go for a brown gold. I know this sounds trivial, but people are smarter than you think. Plus, you get "Phi Tau", most people know Pike more than Pi Kappa Phi.

Good luck to your colony :-). My brother and grandfather are both proud brothers.


eta: Consider a silver perhaps if you go for 3 colors? As in true silver, not grey. In the girl scout tradition, we always said, "make new friends, but keep the old, one is silver and the other is gold."
