The self‐assembly of films that mimic color‐producing nanostructures in bird feathers is described. These structures are isotropic and have a characteristic length‐scale comparable to the wavelength of visible light. Structural colors are produced when wavelength‐independent scattering is suppressed by limiting the optical path length through geometry or absorption.
