I like how much the Boise crowd stands out at our stadium when they all are wearing orange, same with Texas fans and their version of orange, even Utahs bright red really pops when they travel.
I try to go to multiple away games a year, and our colors don't stand out even though we travel well. When we have our annual Royal game I look around the stadium with a smile on my face at how awesome our crowd looks.
Navy is so dull compared to Royal. A year or two ago somebody had a side by side picture showing the difference between BYU's navy crowd and Royal crowd. It makes a big difference if I remember correctly the difference was so stark that people were accusing the poster of photoshopping it (he denied these accusations).
