A bright yellow color of the gas furnace flame is not standard, it indicates incomplete combustion and can be very dangerous. The propane should burn completely blue, otherwise, the burner is not getting enough oxygen, and producing carbon monoxide (odorless, colorless, and deadly).
Sometimes, the air intake ports are adjustable. If so, open them up until the flame burns in a pure blue color. Otherwise, do not use the furnace, it could be dangerous. A gas furnace pilot light can appear partially yellow for a few reasons, and while a slight yellow color is often normal, it can sometimes indicate potential issues that should be addressed.
If you notice that your pilot light is burning yellow instead of blue, contact Prime Air Solutions. The issue can typically be fixed by cleaning out the air intake valve to the pilot light, which should only be done by a professional who can access and repair the part.
