Use abstract representations such as thin entangled lines resembling snares or quicksand, subtle silhouettes of spies in trench coats and fedoras, military symbols like crosshairs, encrypted codes, radar circles, and redacted documents. The color palette should be restrained—monochrome with muted tones like charcoal black, steel gray, olive green, and blood red for highlights. Emphasize tension, concealment, and strategic threat through visual metaphors like shadows, layered shapes, and fading targets. The composition should feel quiet but intense—suggesting danger beneath the surface, like a covert operation or psychological warfare. Avoid clutter or obvious action scenes—focus on symbolism, space, and suggestion." See more
