The color of the hottest flame is blue or violet, often appearing white-blue at its absolute peak temperature. This is due to the phenomenon of black-body radiation and the specific energy transitions occurring in the combusting molecules. In a perfect combustion environment, a flame's color moves through a spectrum as its temperature increases: starting with red (coolest), moving to orange, then yellow, and finally to blue as the flame becomes completely oxidized and its energy output shifts to shorter wavelengths in the visible spectrum.
