What color does the flame on a Freon torch turn?

The flame on a Freon torch turns blue-green due to the specific chemical composition of Freon and the combustion process it undergoes when used in the torch. When Freon is ignited, it produces a distinct blue-green flame, which can be attributed to the presence of halogen elements in Freon, particularly the chlorine and fluorine. These halogens can create a colorful flame that is different from what one might typically see with other fuels. This blue-green flame is both a visual indicator of the combustion of Freon and a reflection of its chemical properties, which distinguishes it from other flame colors seen with different gases or materials.
