Summary:The invention relates to a formula and a preparation process of novel indoor and outdoor cold firework. The novel indoor and outdoor cold firework comprises the following components in percentage by mass: 20%-70% of energetic substances, 10%-40% of an oxidizing agent, 10%-40% of one or more kinds of metal powder, 0%-20% of a flame color reaction material and 0%-5% of a binder. The preparation process comprises the steps of material mixing, particle sieving, firework charging and barrel packaging. Compared with the prior art, the novel indoor and outdoor cold firework of the invention has the following characteristics that elementary substances, compounds and mixtures capable of generating flame color reaction with fireworks during combustion are added, so that the novel indoor and outdoorcold firework has the characteristics of wide color gamut (covering the wavelength range of 400 nm-760 nm), multiple colors, narrow electromagnetic wave full width at half maximum, high contrast ratioof set-off patterns and t
