About

Dr. Esther Perales is a leading researcher in the field of color science and appearance, with a particular focus on the complex optical properties of special-effect coatings. Her work is critical for industries ranging from automotive paints to cosmetics, where precise color characterization is essential. In her highly cited 2016 study, "Color characterization of coatings with diffraction pigments," Dr. Perales tackled the challenge of measuring the iridescence of coatings containing SpectraFlair pigments. By using a robot-arm-based goniometer to capture spectral bidirectional reflectance distribution functions (BRDFs), she established a rigorous methodology for quantifying how these dynamic colors shift with viewing and illumination angles. This foundational contribution, with 14 citations, has provided a vital framework for both quality control and the development of new, visually striking materials. Dr. Perales’s work bridges fundamental optics and applied metrology, making her a key figure in advancing how we measure and understand the appearance of modern, complex surfaces.
