What do different color flames mean?

Flame colour meaning can be indicative of temperature, type of fuel or the completeness of combustion. For example, a blue flame is the hottest followed by a yellow flame, then orange and red flames. Hydrocarbon gases burn blue whilst wood, coal or candles burn yellow, orange or red. Subsequently, is green fire hot? A green flame is just as hot as any other kind of flame, except it has color added to it, due to the presence of a "contaminant". The contaminant may be copper, barium, thallium, barium or Niobium, in order for the flame to show a green color.

You can also ask what is blue fire called?

The University of Maryland's' scientists have discovered a new type of fire, which they have aptly named "Blue Whirl." This new fire is small, whirling, transparent, and blue. Fire whirls tend to burn much faster and hotter than normal fires. In nature, fire whirls can be dangerous when they occur during wildfires. Subsequently, why is fire blue at the bottom? 7. Oxygen supply influences the color of the flame. So candle flames are blue at the bottom because that's where they take up fresh air, and yellow at the top because the rising fumes from below partly suffocate the upper part of the flame.

Keeping this in consideration, does a blue flame have more oxygen?

Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames. And another question, how hot are white flames?
