Good question and pertinent to this event I would say. Runway 20L has what the FAA calls visual runway markings with no 'piano keys'. If the runway had instrument markings like 20R it would be easier to distinguish from the taxiway in my opinion. As you can see from Google Earth, the ramps, runways and taxiways are a hodgepodge of different shades of long narrow rectangles.
Some good information here in what used to be called the Airmen's Information Manual:
