That story is a little bit different than I've come to know. I've always read that the New Orleans/Tulane players went to that department store and bought up all the green ribbon for themselves, leaving the purple and gold for the LSU guys.
BTW, Coates mentions the LSU Gold color as "Old Gold", but the traditional shade of Mardi Gras Gold is the Canary Yellow hue of Gold.
We should all be glad that Boyd didn't get his way with Blue and White.
In reality, based on history, LSU should be the Confederate or Rebel Tigers with the school colors of Grey, (Confedrate/Rebel uniform colors) Red, Blue and White (Confederate/Rebel flag colors) Very similar to our friends up in Oxford.
Anybody know why Ole Miss didn't choose an animal back then for the mascot?
