Alkaline earth metal — Wikipedia Republished // WIKI 2
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.

[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.
