All elemets will give of colors when excited enough. Some take extremely high energy. Elements can be idntified by these colors. Some elements give off their colors easily, such as the metals in column 1 and 2 and copper. When placed in a flame the outer electrons jump to a higher energy level and when they fall back they fall a specific distance or wavelength. . We see it as the color we perceive.

After the firework explodes, the electrons within the metals (typically Mg, Na, K, Zn and such) are excited to higher energy levels. In order for the electrons to get to a ground state they emmit a photon. Depending on the element, the photon has a certain wavelength, and this wavelength determines what color the metal is seen as.

you know what is a colour? you can tell me exactly what it is? The colour is nothing, it isn't a substance or something like this. It doesn't exist. When the light hits an object, The object absorbs (soaks up) some of the co lours of the spectrum and reflects (throws up) others, A tomato, for example, looks red cause it reflects red light back into our eyes, but absorbs the other co lours of the rainbow : orange, yellow, green, blue, indigo and violet light.

Different minerals are added that glow different colors when heated, Sodium is RED, Nickel is green, etc.
