When chemicals present in the fireworks composition get heated, the ions emit characteristic wavelengths or colors of light. This works much like the flame test a method used to identify a substance by its color in a flame. Metal ions are responsi
Looking at Rubidium, Pyrotechnics and Metallic Salts with …
Calcium is orange, sodium yellow, and copper or chlorine give a blue color. Potassium generates a light pinkish violet and rubidium a violet-red color. In 1861, Kirchhoff and Bunsen, in an experiment to extract lithium from the mineral lepidolite dissolved the ore in acid and then precipitated the potassium it contained which carried down another heavier alkali metal.

[Demo] Colored Flames - light | Coursera
Each flame needs time to get extremely hot to yield the maximum emission from the metal. On the camera, this sodium burning looks kind of pink, but in real life, it was quite yellow. Since you have plenty of sodium chloride at home, you can check this one out live, but make sure you have a controlled environment for containing the flame.
