Find the answer:- What is the colour of the hottest flame?

The colour of the hottest flame is Blue and the Blue flame has the highest temperature in the flame spectrum.

Explanation in details

The colour of a flame depends on its temperature and the chemical composition of the material being burned:

• Blue flame: Blue flame indicates the highest temperature. For an example we can see, a properly adjusted gas stove burner burns blue and reaches temperatures of about 1,500 to 3,000 degrees Fahrenheit (800 to 1,650 degrees Celsius).
• Yellow or orange flame: Yellow or Orange flame indicates a cooler flame due to incomplete combustion and the presence of soot particles.
• Red flame: The Red flame represents the lowest temperature in the flame spectrum.

In short we can say that, Blue flames are the hottest because they result from complete combustion, where oxygen is fully utilized in burning the fuel.
