Rockets, shells, or flares should be of what color to indicate an emergency?

• A. Green
• B. Blue
• C. Red
• D. Orange

Answer: (C)

Red is used for distress signals at sea because it is the internationally recognized color signaling an emergency. Rockets, flares, and other emergency devices are designed to emit red so other vessels and rescue authorities can quickly identify a distress situation and respond. Green is associated with navigation lights, blue with authorities in some places, and orange is often used for safety gear or some daytime signals, but not the standard emergency distress color. So red best communicates an urgent need for help.
