colour of flame is blue as well red. why?

Answer Posted / harsha

A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction.
 Metal salts are commonly used; elemental metals are used rarely (e.g. copper for blue flames).
