Have a color contrast thatis readilydistinguishablefrom the surrounding fuselage surface. The contrast must be such that if the re.ectance of the darkercoloris15percent orless,the re.ectance of thelighter color must be at least 45 percent. ”Re.ectance” is the ratio of the luminous .ux re-.ected by a body to the luminous .ux it receives. When the re.ectance of the darker color is greater than 15 percent, at least a 30 percent di.e-rence between its re.ectance and the re.ectance of the lighter color must be provided.]

(2)
Sources ofgeneralilluminationinthe cabinthatprovide an averageillumina-tion of not less than 0.05 foot-candle and an illumination at any point of not less than 0.01 foot-candle when measured along the center line of the main passenger aisle(s) and at the seat armrest height; and

(3)
Floorproximity emergency escapepath marking thatprovides emergency eva-cuation guidance for the airplane occupants when all sources of illumination more than 4 feet above the cabin aisle .oor are totally obscured.
