yes, i do and itโs actually more important than most people think
the blue flame is what u want, what everyone wants. it means the gas is getting enough oxygen so it burns clean and efficiently. it comes from complete combustion which produces heat, carbon dioxide and water vapor... hotter, safer and better for cooking.
the yellow/orange flame is a warning sign. it means incomplete combustion maybe cos the burner is dirty or airflow is blocked. that color can produce carbonmonoxide which is very dangerous for your health. it also wastes energy and gives you bad heat.
