Here's my thought on the subject...there are probably more die-hard GT fans on this board that just about anywhere. I've venture to guess that a majority of the people (who can) on this board attend at least 1 game a season. The fact that you're the only one pushing this (and there are some others that agree), says a lot. It doesn't matter what you wear, as long as it's not the opposing team's colors, just be there.
The fact that other schools have bolder colors (red, safety orange, etc.) has nothing to do with the uniformity of our fanbase apparrel. The reason Clemson, Georgia, etc. show up in our stands is that their colors are much brighter than ours, we don't sell out our stadium, and when we do, we have season ticket holders who sell their seats to whomever. If we all wore gold or white, the opposing fans would show up in stark contrast. Fill the stands with Tech fans and it doesn't matter. Gold, White, Yellow and Dark (Blue or Black) are all acceptable colors to wear, Red would not be.
I think actually wearing dark (man that would be hot on those September Noon kickoffs) would actually mute any opposing colors.
