demonstrated that the color of a given food dye depended on which light was transmitted in the visible spectrum and which light was absorbed. A quantitative measurement of the absorbance spectrum of each food dye was obtained through spectrophotometry.1 Through this method‚ we determined that the wavelength of maximum absorbance of a given food dye was directly correlated to the color of that food dye. Further‚ darker food dyes absorbed more light than lighter food dyes (Table 1). The relationship between
