It indicates that the air hole is closed.
The yellow flame is also called the luminous flame and the safety flame.
It is luminous due to small soot particles in the flame which are heated to incandescence. The yellow flame is considered "dirty" because it leaves a layer of carbon on whatever it is heating.It is considered safe as it is more visible than the near invisible and hot non-luminous flame (it can be obtained by half opening the air hole) as people would not mistake it as switched off and touch it. It is usually not used for heating as it's not as hot as the non-luminous flame(also called the blue flame).
The blue flame is hotter as it produces more heat energy than light energy, comparing it to the yellow flame, which produces more light energy than heat energy.
