There are many myths about the blue turf. Two of the most prevalent are:
There is an NCAA rule banning turf colors other than green, but BSU's field is allowed to remain blue under a "grandfather clause".
The NCAA has no such rule; any school may paint its field any color other than green if it wishes. Though painting the end zones is common, and schools have wide latitude in how to do so (for example, Neyland Stadium has its end zones painted in its distinctive orange and white checkerboard scheme), only BSU has chosen a non-green color for the field itself.
