In 2011 Boise State obtained a federal trademark registration for “the color blue as applied to artificial turf”. Perform an internet search for “Blue Turf” and all you will see is Boise State references.
The NCAA does not ban colored fields, but the NFL does. It’s known as the “Boise State Rule“.
It is a myth that ducks fly into the turf mistaking it for the river. However,”The Myth Is True, Ducks Do Crash On The Blue”, is still one of the best selling BroncoShop game day shirts. It was released for the home game against Oregon on September 3, 2009. If you have any suggestions for fun slogans or designs for the next season’s game day shirts, please email firstname.lastname@example.org.
