Semaphore Signal Illustration

An illustration featuring two distinct flags, each divided diagonally into red and yellow sections. These colors, red and yellow, are prominently used in various forms of visual communication, including the International Maritime Signal Code (where this design specifically represents the 'Oscar' flag for "Man Overboard") and traditional semaphore signaling systems. The simple yet striking design on a black background draws attention to the elements of flag-based communication.
