ABSTRACT: Pyrotechnic formulas designed to produce colored flames are well known, but the trends in color quality due to individual formula components are less well understood. This paper presents spectrometer work done to record spectra and processes them into chromaticity coordinates. Major formulas of the basic additive colors of red, green, and blue were tested and compared. Impact sensitivities were gathered for those major formulas. Then single suitable formulas were chosen for the basic colors, which were then systematically altered and measured for color quality performance. The formulas were altered to investigate the role of oxidizer to fuel ratio, chlorine donor content, colorant content, and colorant source.
Keywords: color purity, chromaticity diagram, chromaticity coordinate, star formula, flame emission
