How are different colours of light produced
WebThere are two main mechanisms of color production in fireworks, incandescence and luminescence. Incandescence is the emission of light caused by high temperature. As a substance heats up it emits colors in different stages starting with infrared, then red, orange, yellow, and white as it becomes increasingly hotter.

WebAn optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings. The optical properties of filters are completely described by their frequency response, which specifies how the magnitude and phase of … The primary colours of light are red, green and blue. Mixing these colours in different proportions can make all the colours of the light we see. This is how TV and computer screens work.
