What does the fire for smoke signals look like?

The fire used for smoke signals typically consists of a small, controlled blaze made from dry wood or other combustible materials. To create smoke, green vegetation or damp materials are often added to the fire, producing thick, white smoke that can be seen from a distance. The smoke can be manipulated by adjusting the amount and type of material used, allowing for different patterns or signals to be emitted. This method has been historically used by various cultures for long-distance communication.
