Role of dye concentration as well as fabric GSM on relative color strength and color coordinates were examined by spectral analysis. Spectral analysis of cotton fabric dyed with C.I. Reactive Yellow 145 has recorded maximum absorption at 430nm wavelength by using Kubelka-Munk theory, which allows the prediction of spectral reflectance of colorants in terms of absorption and scattering coefficients at same wavelength. The dyed fabric samples were tested in Datacolor 650(reflectance spectrophotometer) to get the difference in color coordinates.
