Explanation:
Candles produce light by releasing heat. A candle flame consists of three zones. Each zone has different temperatures and colors.
The first zone is called the outer zone
The second zone is called the middle zone.
The third zone is called the Inner zone
The outer zone is blue in color, due to complete combustion. This zone is the hottest zone.
The middle one is in yellow color, which is the bright part of the flame. It is moderately hot and partial combustion of fuel takes place.
The least hot region of the flame is innermost zone. This inner zone is black in color due to the presence of unburnt wax vapors.
