This convection is what draws out the tongues of flame. The hotter flames and sparks rise up, creating a vacuum effect which draws cooler air into the base of the fire, continuing the combustion cycle. Fire dissipates when the combustibles are exhausted. Because of this glowing combustion, colors ranging from whitish yellow to dark orange are primarily what you’ll see in a natural fire. Fires do not become dark red or black as they cool. As the flames rise and lose their heat, they become a darker orange, but never as dark as a molten or superheated material does when it cools.
