Flame color of the combustion of fuel gas and air

What is the color of the flame during chemical combustion, when the oxygen in the air reacts completely with the fuel gas? What is the color of the flame during superchemical combustion, when there is an excess of oxygen in the air? And what is the color of the flame during subchemical combustion, when there is a deficiency of oxygen in the air?

The color of the superchemical combustion flame is blue； The color of the subchemical combustion flame is light red ； When the fuel gas reacts completely with the oxygen in the air, that is, during chemical combustion, the flame appears light red-blue. Do you marine friends think this statement is correct?

Reply to 4# Sulfur Blind: I read in some materials that the color of a hyperchemical combustion flame is blue； The color of the subchemical combustion flame is light red ； The color of the flame when the fuel gas reacts completely with the oxygen in the air, that is, during chemical combustion, is a light red-blue

Peroxide gives a bright white color, while natural gas has a pale blue hue (heavy hydrocarbons, on the other hand, result in a red color); low oxygen levels result in a yellow to red color, depending on the degree of oxygen deficiency. To answer this, one needs to understand how colors arise, which involves physical knowledge
Brother, I agree with you, but could you please explain how colors come about? Why does this color appear?
When the flame turns red and black smoke emerges from the chimney, increase gas degumming and boost the heat-supply steam； When the flame turns red and the furnace chamber darkens, if the gas flow is too high, reduce the gas supply or increase the air flow ； When the flame turns white, flickers unevenly, there is a low amount of gas or an excessive amount of air, increase the gas supply or reduce the air flow ； When the flame carries sparks, it indicates that the gas contains water, and dehydration should be carried out immediately.
When the fuel gas in the heating furnace burns normally, it should be blue-white; the flame turns blue when there is an abundance of oxygen in the air, and it turns yellow when the oxygen level is insufficient
