We present a method for estimating the parameters needed to compute a reflection model of thin-film interference, using multiple RGB values of the iridescent effects obtained from images taken with an RGB camera to render the iridescent effects of a real object. In the field of optics, many effective methods have been proposed to estimate the thickness and refractive index of thin films, assuming that the refractive index of the base material is known. We assume that the complex refractive index of the base material is also unknown. We consider the parameters related to thin-film interference such that the RGB values of the image appear as the iridescent effects as vectors and find the combination of vectors with the smallest Euclidean distance. We consider that we have estimated the parameters that appears an iridescent effect close to the reference image.
