Answer 2

Answer:

Colours that come from fire works are because of some metals in them .

Explanation:

Generally, fireworks have two main components: pea-sized salt pellets for the colorful explosions, and black powder to shoot those pellets into the sky. These are encased in a cardboard shell with a fuse in the middle.

Some metals can generate multiple colors, depending on how hot they get. We see these different light wavelengths as different colors.
