A properly adjusted flame on a bunsen burner would have a flame that is blue. It would also appear that there is a lighter blue flame in the center, usually referred to as an inner blue cone, the hottest part of the flame.
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.
If there is not a sufficient supply of oxygen, the flame will be smoky from excess of carbon.
The yellow flame because that is the safety flame

I'm assuming that we're talking about Bunsen burner... If the flame is yellow and smokey, there is too much gas to oxygen ratio. Cut back on the gas flow.
The silent flame on the Bunsen burner is the yellow/orange flame.
As a safety flame, keep it on this if the burner is not in use :)
yellow flame
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.
No, a yellow flame is colder than a blue flame.

The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.
The coolest flame on the Bunsen burner is the yellow-orange flame - approx. 300 0C.
