Flames

: A flame consists of hot gases (like carbon dioxide and water vapor) and often solid particles of soot. The color emitted depends on the temperature: lower temperatures produce red or yellow, while higher temperatures shift toward blue.

A flame is a visible, gaseous part of a fire caused by a highly exothermic chemical reaction—typically combustion—occurring in a thin zone. It represents the point where fuel particles have been heated enough to emit light in the visible spectrum. The Science of Flame Flames

Beyond physics, "flames" carry deep symbolic meaning in literature and social contexts: How to create multicolored campfire flames? : A flame consists of hot gases (like
