innermost zone : black colour , unburnt part, least hot

middle zone : partialcombustion occurs, yellow colour, moderately hot

outerzone : complete combustion , blue colour, hottest part.

Outer Zone: This zone is blue in colour. It is the hottest part of the flame, because complete combustion takes place in this zone.

Inner Zone: This zone is dark in colour. This is the coolest part of the flame because no combustion takes place in this zone.
