blue

This is black fire. When you mix a sodium street light or low-pressure sodium lamp with a flame, you’ll see a dark flame thanks to the sodium and some excited electrons. “It’s strange to think of a flame as dark because as we know flames give out light, but the sodium is absorbing the light from the lamp.

The coldest flame color will be black since the flame is so weak that it barely produces light. Color also tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C).
