Is a yellow gas flame dangerous?
A red or yellow flame is a flame being starved of oxygen, creating incomplete combustion. This flame is dangerous as it produces more poisonous carbon monoxide gas.
What color should your furnace flame be?
The burner flames from your natural gas furnace should look blue or almost completely blue. A healthy natural gas furnace flame is characterized by a roaring blue flame with a light blue triangle in its center. There may be a tiny tip of yellow.
Is orange gas flame dangerous?
The flames from a natural gas stove can tip you off to a possible hazard. If you see orange flames instead of blue flames, the burners may need cleaning or adjusting. The orange color alerts you to your gas stove’s improper combustion, which may emit unsafe levels of carbon monoxide gas.
Should a gas flame be blue or yellow?

What conditions result in a blue flame?
You get a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion. When you do have sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
What should a gas flame look like?
A healthy, properly burning flame on gas appliances should be blue in color, sometimes with a tiny tip of yellow, with a little light blue triangle at the center. This blue color flame indicates that there is safe, efficient and more complete fuel combustion.

What color flame is the coolest?
Although red usually means hot or danger, in fires it indicates cooler temperatures. While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames.
