There is a lot of red in it, but there's good reason for that. If you attend a U of A sporting event, fans almost universally wear red. They are, in fact, encouraged to do so. I had seats at U of A v Washington State two weeks back and it was simply a sea of red throughout the stadium.

That's why I went with red as the dominant color. While red and navy are the school's colors, the red seems to get top billing.
