Each element give off a particular color when heated in a flame. (Some are colorless). Copper gives off a green flame but to do that there must be some copper compound IN the flame. (there are many other elements that also could be causing a green flame).
Answer 1: Blue flames come from very hot, complete burning of air and fuel. Orange color comes from cooler spots in the flame where fuel isn't being totally burned and these produce a little bit of soot and smoke. The color of the flame is related to the heat of the flame. Think about the colors of different hot things: the Sun is white or yellow, a hot stove is red, a camp-fire is orange, and a gas flame is usually blue. These colors come from different kinds of a light and different places in the electromagnetic spectrum.
