Emergency outlets use a color cue to show they stay powered during outages. Red is the standard color for these outlets because it instantly signals to staff which receptacles are tied to the backup power system and will continue to supply life-saving equipment when the regular electrical supply fails. This quick visual distinction is crucial in emergencies, helping ensure critical devices remain operational. Other colors like blue, green, or gray are used for different purposes and do not indicate emergency power, so they wouldn’t serve the same safety function.
