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.
The chemical that makes a firework green is typically barium compounds, such as barium chloride or barium nitrate. When the firework is ignited, the heat causes the barium to emit green light.
A firework takes off when it is ignited, causing a chemical reaction inside the firework. This reaction produces gas rapidly, building up pressure inside the firework until it eventually forces the firework to launch into the sky.
Yes, the gunpowder reacts with oxygen. The oxygen comes from oxidizers perchlorates, chlorates, nitrates, permanganates, chromates or oxides.In propelling the rocket, potassium nitrate is used with black powder. Chlorates or perchlorates are used for the explosion as it reacts with carbon and sulfur rapidly. For the different colours of firework, various metal salts are used.
When a firework "reports," it means that it makes a loud noise, typically a bang or explosion, as part of its visual display. This is a common effect in fireworks shows, and it adds excitement and spectacle to the overall presentation.

Different colours appear because it is the way the human eye perceives them. Colours have different wave lengths and human's eyes can see that which makes you see it as a colour. The thing that makes colours different is the size of the wavelength.
It splits into the colours that make it up, so white light makes a rainbow, and different colours produce different results.
They put chemicals in it.

light refracted by raindrops appear to be different colours
The song Firework is written to encouarage people to just be themselves because every one is different. We are all unique in our own way an that is what makes us all awesome.
A metal called aluminium.
barium nitrate
They just like different colours and it makes it look cool
It makes it easier to identify the different groups visually.
red food colouring;)
