A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.

The hottest Bunsen flame is blue in color. It indicates complete combustion of the gas due to the high temperature.
The unsaturated hydrocarbons are mor tangled up so it's harder for the oxygen to get in and break the bonds. Because of this some large sections of the hydrocarbon floats up before being broken, making the flame sooty.
When the airhole on a Bunsen burner is open, the flame color is blue. This indicates complete combustion of the gas.
A blue flame is produced upon ignition of butane, indicating complete combustion with efficient energy release.
Non-luminous flame
The color of the flame can indicate the completeness of combustion. A blue flame typically indicates efficient combustion with minimal smoke, while a yellow or orange flame can signify incomplete combustion resulting in more smoke being produced.
The flame will be blue when the hole is fully open on a Bunsen burner. This is because the complete combustion of the gas produces a hotter flame with a blue color.
The flame produced by burning acetylene gas is typically colorless when burned in pure oxygen. However, if burned in air, it can produce a slight yellowish flame due to incomplete combustion, which may also contain some soot.
