Dress codes even apply to coaching legends, apparently.

Former Notre Dame coach Lou Holtz was made to change out of a blue sweater when visiting Ohio State football practice Saturday, according to reports.

Ohio State coach Urban Meyer has a legendary "no-blue" dress code that applies to visitors, as well as his players and staff.

Blue, of course, is the color of chief rival Michigan.

Holtz changed from a light-blue sweater into a scarlet-and-gray pullover jacket.

Holtz is making the rounds this offseason. He was a featured guest during Michigan's "Signing of the Stars" event at Michigan in February.

Color dress codes aren't uncommon on college campuses.

Michigan basketball coach John Beilein chided a reporter this season for wearing a green shirt to a press conference, and even tells players' families attending games to wear any colors but green (Michigan State) or red (Ohio State).
