We propose a colorimetric method for process control of metallic coatings. Color coordinates of automotive metallic finishes follow fluctuation scaling. Lightness variations are related to a self-similar stochastic process. The exponent of fluctuation scaling is sensitive to different flake-shaped pigments.
