Only ion''s/metal loosely held electrons we witness become excited, we are witnessing the energy changes in the ion, doesn''t matter what compound it is.

What color does copper burn in fire? - Quora

What you probably mean is copper salts, which are used to color flames. There are two commonly used flammable copper salts and they produce different colors. Cupric chloride burns blue. Cupric sulphide burns green. There are other metal salts that burn other colors as well, for instance Potassium chloride burns purple. You can find a table here.

experimental chemistry - Why flame color of salts is

2019-3-19 · If a pure metal is heated up in a flame, we see it giving the flame a characteristic color, e.g. $\ce{Na}$ burns yellow. If a salt, e.g. $\ce{NaCl}$ or $\ce{Na2SO4}$, is heated up, resulting color to a greater degree still is that of the pure metal. Although the color does change depending on the anion, this effect is usually not much pronounced.
