Non-iridescence

Non-iridescence refers to the absence of iridescence, the optical phenomenon where the surface of a material displays multiple colours due to the interference of light. Materials exhibiting Non-iridescence do not shift in colour when viewed from different angles; their colour remains consistent. This lack of colour play results from a uniform surface structure, preventing the light scattering and interference crucial for iridescence. Non-iridescent surfaces appear as a single, stable colour. They can still have pigments and other non-iridescent colour properties, for example, a dull red painted wall.
