A fire pattern refers to the mark or impression created by fire as it spreads across a surface. This pattern can provide crucial information about the fire's origin and its behavior during the incident. Fire patterns are formed as different materials respond to heat in various ways, leading to distinct signs on surfaces like walls, floors, and ceilings. Investigators analyze these patterns to determine how the fire started, its growth and spread, as well as potential accelerants used, which are all vital elements in arson investigations.

Other options do not accurately capture the concept of a fire pattern. The sound of fire, while an interesting aspect of a fire scene, does not relate to the physical evidence that fire leaves on surfaces. Color variations may indicate different degrees of burning but do not constitute a defined pattern. Lastly, the smell of smoke, although indicative of a fire having occurred, does not create a visible impression or mark related to the fire's behavior or characteristics.
