I missed this change when it was first announced, but I see from today's Indiana at Illinois game that the Fighting Illini have a new court that includes painted-in orange keys and blue lettering. A schematic of the new court is available here. The previous design, which almost entirely banished the blue, is shown here.
The Murray State (Kentucky) Racers, seemingly in keeping with their horse-racing theme, have a diamond-based design in the keys, similar to what might appear on jockey silks. Based on this video clip, I've created the following schematic.
