What color is the international distress signal flag?

The international distress signal flag is actually a square flag that is colored in red with a white square in the center. This distinctive flag is recognized globally as a symbol for distress and indicates that a vessel is in need of assistance. Its bright red color ensures high visibility, making it easy to spot against various backdrops, whether at sea or on land.

The options of white, green, and orange do not align with the recognized signals for distress. White is generally associated with surrender or peace, green often indicates safety or the absence of danger, and orange can be used for signaling but is not designated specifically for distress in maritime contexts. Understanding what the distress signal flag looks like is crucial for mariners to communicate their need for help effectively.
