What makes different colours in a firework?

Answer 1

We did this experiment in chemistry (well something like it). There's different chemicals that is out into the powder. The chemicals react differently when exposed to heat therefore when exposed to the extreme heat of the small explosion, the chemicals give off a certain color. The color depends on the chemical.

Answer 2

Different colors in fireworks are typically produced by adding specific chemical compounds to the fireworks. When these compounds are heated, they release energy in the form of light of a specific color. For example, strontium compounds produce red, barium compounds produce green, and copper compounds produce blue. By combining these compounds in different ratios, a wide range of colors can be achieved.

Answer 3

Different chemicals, usually metals, added to the powder. When they burn, the metals influence the color of the flame.
