In a flame, the color indicates the peak wavelength of the light being produced, which correlates directly with the thermal energy available in the reacting gases. Yellow flames, such as those from a gas stove, reach temperatures of 1,200°F to 1,300°F (650°C to 700°C).

However, when comparing the general progression of wood fires to gas fires, the presence of a blue core within a yellow flame is the surest visual indicator of the highest temperature region. White flames indicate a significant jump, often exceeding 1,300°F (700°C) and approaching 1,500°F (815°C).
This specific color is often observed in applications requiring extreme thermal energy. For instance, copper compounds burn with a characteristic blue-green flame, while lithium produces a bright red.

The intense heat required to produce these colors means they are less common in everyday scenarios but are a clear indicator of extreme thermal activity in industrial or laboratory settings. These are the hottest flames achievable with standard combustion, often exceeding 3,000°F (1,650°C).
