The flame on an LPG stove appears blue because of complete combustion. But the main reason why a gas flame is blue is because of the low carbon content in the gas; fuels with higher levels of carbon will produce a red/yellow flame; therefore this is why the flames of matches, coal and oil lamps have yellow/red flames as opposed to blue flames.

Complete combustion

LPG does not emit soot or pollutants because the hydrocarbons (propane and butane) present in LPG burn completely when combined with oxygen, producing no emissions and no smoke. The process of burning LPG in this manner is called "complete combustion," which gives rise to a blue/white flame. Thus, a "blue flame" indicates that the gas is in the process of complete combustion.
