REFERENCE: A blue flame colour means complete combustion. This indicates that the gas is being burned efficiently without any unburned and wasted gas.
A red or yellow flame is a flame being starved of oxygen, creating incomplete combustion.

BLUE FLAMIN'
You came to me in a slow burnin’ way
Parched and left to decay
A starved of oxygen kind of soul
Across the floor, through the door
Your face came into view
All alone in a ghostly hue
An ignition of interest
An unexpected spark
A small yellow flame
Slow and steady from first mark
Catching and burning
Tender in motion and rising high
More air, you burned fast
Yellow flamin’ up to the sky
There for a while.
Glimpses of the blue flame
A phantom in fright
