Red pyrotechnic flames are mostly produced using strontium compounds. Flame color quality is dependent on the chemical composition of the mixture. The emission spectrum produced by strontium monohydroxide (SrOH) and strontium monochloride (SrCl) species in red colored flames was measured, analyzed, and compared. Chlorine was introduced into standard composition of anhydrous strontium nitrate and shellac using three different classical oxidizers - chlorine donors: potassium chlorate, potassium perchlorate, and ammonium perchlorate. Color points and excitation purity in CIE 1931 chromaticity diagram were calculated.
