How are these colours produced?

To understand the science of colours, we must first know something about the nature of light. Light is a form of energy that behaves like a wave. Visible light of different wavelengths is detected by our eyes as a range of colours. Of the light that we can see, violet has the shortest wavelength and red has the longest.

Fireworks generate light and colour due to the physical and chemical attributes of specific compounds. When these compounds are heated and combusted they give out energy, some of which may coincide with the wavelengths in the visual region of the spectrum.
