Buoyant smoke signals used during daytime are what color?

Daytime signaling relies on color contrast, so buoyant smoke signals are orange because this hue stands out most clearly against the blue of the sea and sky. The bright orange plume is easier to notice from a distance in daylight, making it a reliable distress marker. Red flares are more typical for nighttime signaling, where a bright red glow is visible in darkness, while blue or green smoke would not contrast as well with the water and sky. So orange is the best choice for daytime buoyant smoke signals.
