A one story building lies on a corner of a hill. The doors are red, the arch ways are blue, then floor is yellow, the walls are red, the cieling is blue, the design of the walls are yellow, the fire alarms are red, the pool is blue, the light bulbs are yellow, the books are red, the book shelves are blue... what color are the stairs?
