Why is Boise State's field blue?

Answer 1

Apparently at one point they were going to put down some new AstroTurf, and it was going to cost $750,000. the AD thought it was a shame to spend that much money when no one would even notice that anything had changed. So, since everyone already knew that the field was going to be AstroTurf and not real grass anyways, they decided to make the turf blue, that way people would notice that the field was new.
