The analysis

The claim states that the orange flame color of certain rocket engines results from the combustion properties of its propellant mixture (such as the presence of specific metal species or carbon emission). This is a well-known scientific principle regarding emission spectra and combustion chemistry, rendering it common knowledge that does not require specific paper citations from the provided literature.
