IMO neither are "traditional." The one time that Tech wore blue jerseys that should have been enough to end it forever (but it wasn't) was in 1942. Tech was #1 in the country and headed to the Rose Bowl, pending the results of the Georgia game. Alexander was HC, but he was sick, and Dodd coached that game, choosing blue jerseys for the team to wear. Georgia slaughtered us in Athens, and they ended up going to the Rose Bowl instead and a share of the NC with tOSU. I don't know when we next wore blue jerseys again after that, but again IMO we should never have. As far as distinguishing what the trim color was, when I was in school in the 60s, and up until blue was "officially" adopted, the trim was definitely black. I had (no longer do) a jersey and other gear in my possession, and there was no doubt about the color.
