What colour the flame is has totally got to do with how much oxygen is allowed into the Bunsen, the flame can be anywhere between a bight orange to blue, all the way to being almost unnoticeable. This is what make them dangerous if unattended as you wont know there burning until you are. Low air easily visible flame, High air flow, and it becomes very difficult to see.
The color of a flame when a Bunsen burner has its air hole open is blue. The flame is usually blue because more oxygen is getting into the Bunsen burner.
the color of the flame is a violet - blue color
inner= dark blue outer=light blue
The flame is blue.
The flame is yellow.

When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
With oxygen closed off and a yellow flame the temperature is about 1000 degrees Celsius.
The first step in lighting a Bunsen burner is to check for safety. Next you make sure the holes are closed, light the match, turn on the gas tap, and put the match to the top of the burner. Once lit, you adjust the flame.
It's the part of the Bunsen burner which lets in air, adjusting the strength of the flame. basically the hole at the bottom with the twisty bit.
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.
when you light up the burner you should see that the Bunsen burners air hole is closed that is the safest flame
It is closed to make a safety flame.
It is a luminous yellow flame. 🔥
its a orange colour when closed and a blue colour when is open

In a laboratory under normal conditions and with a closed oxygen valve, a Bunsen burner burns with yellow flame (also called a safety flame). This is due to the burning of very fine soot particles that are produced in the flame. With increasing oxygen supply, less black body-radiating soot is produced due to a more complete combustion and the reaction creates enough energy to producing a blue appearance flame.
it's to prevent a strike-back
The "air-hole" of a bunsen burner allows some of the flame to escape so that the heating flame does not become too hot. A flame that is too hot can damage laboratory equipment. When the air hole is closed it is a yellow sooty flame like the fires we have at home.

Yes,it can .But it might take longer time to heat
It is less hot
