Answer #3

Depending on the fuel being burned and the amount of oxygen enrichment, the flame will give off a different spectrum of light. This spectrum will follow the pattern of a rainbow. Coldest to hottest: Red Orange Yellow Green Blue Indigo Violet White

Also, combustion of certain materials will result in different colors of flames based on the color they turn when they oxidize. Magnesium burns white, copper burns green, cobalt burns blue, iron burns red, etc.
