A blue flame typically indicates a cooler temperature compared to other colors like red or yellow. Blue flames often burn fuel more efficiently due to the higher oxygen content, resulting in a more controlled and cooler burn.
The hottest flame is blue (or a shade thereof).
In industrial processes, such as oxy-fuel welding and cutting, the base of the flame tends to be closer to the ultraviolet range. Frequencies in this range and higher are not considered "colored light."
Higher frequency photons (ultraviolet to gamma rays) tend to have more energy, which is the reason ultraviolet light gives you sunburns, while infrared, micro, and radio waves do much less harm.
The hottest flame is a transparent blue/white colour. A darker blue flame usually shows unburnt gas.
The orange-yellow (or even red-black) gas flame is the coolest (350oC), the white-blue flame is much hotter.

What is the coolest flame on a Bunsen burner a spirit flame or a gas flame?
The external part of the flame is the coolest.
In the Bunsen burner where is the flame hottest?
The hottest flame is the blue flame and the coolest flame is yellow.
What cause the luminousity of the flame?
The color of the flame depends on the temperature, fuel nature, composition of particles in the flame, oxygen concentration.
What is the color of the coolest stars?
The coolest stars are red in color. They are classified as red dwarfs and have surface temperatures ranging from about 2,500 to 3,500 degrees Celsius.
Why does wood flame is yellow where as natural gas flame appears blue?
Answer:Color of a flame depends primarily on its temperature. In the visible spectrum, red is the coolest, blue the warmest. The yellow you see in burning wood is from its lower temperature and the incandescence of fine particles in the flame called soot. The soot is formed because of a lack of oxygen during combustion. Natutral Gas burns at a higer temperature and tends to burn more completely in the environments we use it in, so you see a blue flame and little to no soot.
What color flame burns the coolest?
A lazy yellow flame is the "coolest" flame.
Which portion of the luminous flame is the coolest?
For a Bunsen burner the lowest temperature is in the extreme lower part of the flame.
What is the coolest flame on a Bunsen burner a spirit flame or a gas flame?
The external part of the flame is the coolest.
How are color and temperature relateted?
Blue = Hottest Red = Coolest.
Is the purple flame the coolest flame?
Yes.
What is the coolest flame a Bunsen burner produces?
The coolest flame on the Bunsen burner is the yellow-orange flame - approx. 300 0C.
What is the coolest portion of a Bunsen burner flame?
The coolest flame on the Bunsen burner is the yellow-orange flame - approx. 300 0C.
What is the coolest flame on a Bunsen burner?
yellow flame
Do different colors of fire have different heats?
Yes, the color of fire can indicate its temperature. Blue flames are typically hotter than yellow or orange flames because they burn at a higher temperature. The color of the flame is determined by the elements being burned and the amount of oxygen available for combustion.
What is the color of a cool temperature star?
Red is the coolest star and blue is the hottest.
Stars of what color have the coolest surface temperature?
Red from all data I have looked at.
In the Bunsen burner where is the flame hottest?
The hottest flame is the blue flame and the coolest flame is yellow.
