These are my thoughts as a steel fabricator. Using an oxygen acetylene cutting torch as an example... A very rich mixture of gasses coming out of the torch is Orange with much Black smoke. A high oxygen mixture is Blue White.Setting the mixture At the optimal point between an Oxidising flame and Carburizing flame is ideal.
I believe that effciency in an engine may be measured thus, and exhaust coulor be matched accordingly.
Thankyou for your patience
