We started off as a colony of Alpha Phi from the start. However, the Gamma Beta chapter of Theta Xi at Florida Institute of Technology started as a local fraternity, Delta Delta Tau, and their colors were blue and yellow. I don't know when they were founded, but they had a 30th anniversary celebration last year and something like 80 guys showed up!

I think that is awesome.
Their pledges still wear the Delta Delta Tau shirts.. it's cool.
