Determine Best Color For Common Area Hallway With Elevator In A Myrtle Beach Condo?

The hallway is 6 feet wide and 25 feet long. Here are colors that I am working with that I amnot able to change. The first 19 feet of the floors are gray tile with a green hue and black grout. The last 6 feet of the floor has carpeting with a blue hue.
There are two elevator shafts that are painted with oil based paint a dark brown. The wall opposite of the elevators has molding in the middle of the wall. The wall with the elevators does not have molding in the middle of the wall.
The hallway lighting is decent but I would like a paint color that would make it look brighter. The one exterior wall has a 3 foot wide full length window but based on the time of the day the hallway can look darker.
Remember that all I can change is paint color and not anything else since this is a common area. Please give your advise on the paint colors to use below and above the molding. Should they be the same paint color or different. What Lowes paint color(s) would you select?
