What color is the first sub pennant?

• A. Red and Yellow
• B. Blue and White
• C. Yellow and Blue
• D. Black and Yellow

Answer: (C)

In naval signaling, pennants use color patterns to identify units or roles at a glance. The first sub pennant is the two-color design in yellow and blue, chosen so submarines are instantly recognizable to signalers and other ships, even from a distance or in rough weather. The high-contrast yellow and blue makes it stand out against the sea and the mast, which is why this combination is used for the first sub pennant. The other color pairings correspond to different pennants or are not used for the first sub pennant, so yellow and blue is the best, most recognizable choice.
