Does talc change color if heated?

Why do cations emit colors when heated in a Bunsen burner flame?
Transitions between electronic energy levels release electromagnetic radiation corresponding to the energy difference between the levels. The heat promotes the electrons to the higher level; when they drop back down to the lower level a specific color of light is emitted.
Which elements give off a color when heated and what color?
Different elements produce different colors when heated. Here are a few examples: Lithium produces a red flame Sodium produces a yellow flame Copper produces a blue-green flame Potassium produces a lilac flame Barium produces a pale green flame
