Each base must establish either red or green as the standard lettering
color. Installations in or near jurisdictions with established exit sign
lettering colors should adopt similar red or green standards. Do not
replace existing exit signs meeting NFPA 101 requirements simply to
standardize sign colors. When signs must be replaced for other reasons,
use the installation color.
Installations overseas can use different colors, pictorials, or bilingual
lettering as necessary to comply with local national standards. All exit
signs must be immediately obvious as an exit marking to a recently
transferred or visiting U. S. citizen. Additional markings are permitted to
comply with host nation standards.
