Finally a chance to weigh in....
Blue is bad because it's ubiquitous.
Every HS, former football power,and your aunt Mary wears blue and gold.
Other schools that have gold without blue in their scheme have similar issues with the apropo shade. See Pitt, Navy, Mizzou.
If you're a good Jacket you'll wear something in yellow/gold as long as it's bright and stands out.
Don't get lost in the details. I fell in love with Tech after seeing Wm. Bell run roughshod over Nebraska in Blue Jerseys, but as an undergrad I was in Yellow or White for every game. Follow SHW and just wear a yellow tie.
