UL94 50W flame effect

Bunsen burners are common fire test instruments, such as UL94, which typically use methane as a gas and the flame is blue.
But blue is the subjective feeling of the human eye, and the color is related to the background and lighting.
Is there a more objective way to evaluate the color of the flame?
