Slightly above the base of the fire begins the continuous flame region. Here the temperatures are constant and are slightly below 900°C.
Above the solid flame region is the intermittent flame region. Here the temperatures are continuously dropping as one moves up the plume. The visible flame tips correspond to a temperature of about 320°C.
Finally, beyond the flame tips is the thermal plume region, where no more flames are visible and temperature continually drop with height.

The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C).
