FAQ

Multi-layer coatings on mica (e.g., TiO₂ + Fe₂O₃ + SiO₂) create stacked thin-film interference systems. Different layers reflect at different wavelengths; as viewing angle changes, the dominant interference wavelength shifts, producing the colour-travel effect from purple at face angle to green at flop angle.
