Of course you don't care what was written during the first season of GT football. It destroys the basis for your constant rant.
Besides, don't be obtuse. Your comment was that blue was always a secondary color. I think that article pretty much refutes your statement. I'll take a primary source from the era in which the colors were first decided over you repeating your opinion over and over. Just because you say it, doesn't make it so. I find it humorous that you continue to fight a losing argument in the face of overwhelming evidence.
As for merchandise, don't fool yourself. The retail stores will stock whatever sells. If the overwhelming option is blue, it's because that's what's being sold the most. If the white and gold options were continuously being sold out, the retailers would stock more of that merchandise. They don't care what Georgia Tech colors are; they're in business to sell shirts, shorts, pull-overs, hats, etc. They want to move as much merchandise as possible. The fact that most of what you see is blue is a direct relation to the fact that most people prefer blue.
As for the fight song, it was created in 1919, 28 years after the first football team took the field. By that time, blue had been transitioned to a secondary color. I've never argued that blue wasn't a secondary color today: it is, and I have not qualms admitting that.
