An extrinsic optical fiber sensor method for color matching assessment of textile dyes using their Ultraviolet-Visible-Near Infrared (UV-Vis-NIR) transmission spectra is proposed in this paper. Spectra values are converted to CIELAB coordinates to improve the calculation of color differences. Color matching assessment is finally performed using Receiver Operating Characteristic (ROC) curves to find the optimum discrimination threshold between different dye samples.
