Yellow/Orange. The blue one is harder to see and hotter.
The blue flame.

The safety flame on a Bunsen burner is a low, cool flame that helps prevent accidental ignition of flammable materials. It does not produce enough heat to effectively heat an object. To heat an object, the Bunsen burner must be adjusted to produce a hotter, blue flame by increasing the airflow.
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
No. The blue flame is called the roaring flame because it makes a sort of hissing sound, it is also not called the safety flame because it emits very little light so it is a hazard. It is a hazard because you can not see it very well so it is dangerous.
The flame on a Bunsen burner should be blue when not in use. If the flame is yellow, it may indicate a problem with the burner, such as not enough air mixing with the gas, which can be a safety hazard.
A cool Bunsen burner flame typically appears yellow.
The roaring flame on a Bunsen burner is typically blue in color.
its a orange colour when closed and a blue colour when is open
The blue flame.
As a safety flame, keep it on this if the burner is not in use :)
When the airhole on a Bunsen burner is open, the flame color is blue. This indicates complete combustion of the gas.
The safety flame on a Bunsen burner is used when the burner is not in use to prevent accidental fires. It is a small, non-luminous flame that burns with a blue color and is created by adjusting the air hole on the burner.
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
Blue and purple
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
It will show it's own spectrograph pattern.
