What color is the strongest flame?
light blue
The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you get from the center of the flame, the lower the temperature will be.
Which is hotter blue or red flame?
Hotter fires burn with more energy which are different colors than cooler fires. Although red usually means hot or danger, in fires it indicates cooler temperatures. While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames.
What does a blue flame mean?
complete combustion of

Pure hydrocarbons like methane (refined natural gas), propane, butane and ethane gases also burn with a blue flame. For Natural Gas (Methane), the blue flame temperature is about 1,960°C.
What Colour fire is the hottest?

Do purple flames exist?
Purple flames come from metal salts, such as potassium and rubidium. Purple is unusual because it’s not a color of the spectrum. Purple and magenta result from a mixture of blue light and red light. For this project, the fire color comes from the emission spectra of safe chemicals.
What does a green flame mean?
In ordinary flames, a green color indicates the presence of copper, or a copper compound. In pyrotechnic flames (including fireworks), green flames are always made with barium compounds (along with a source of chlorine.) Many people mistakenly believe that copper compounds are used to make green flames in fireworks.
What does yellow flame mean?
incomplete combustion
A red or yellow flame is a flame being starved of oxygen, creating incomplete combustion. The flame will be at a much lower temperature and will seem more sooty. The yellow colour comes from the soot particles produced by the flame. This flame is dangerous as it produces more poisonous carbon monoxide gas.
