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.

Non-iridescence meaning with examples

• The matte finish of the paint on the car showcased Non-iridescence, providing a solid, unchanging black regardless of the viewing angle. Its colour didn't shift or shimmer.
• Unlike the iridescent feathers of a peacock, the pigeon's feathers display non-iridescence. Their grey hue remained constant, lacking the vibrant, colour-changing effect.
• The ceramic tiles on the kitchen floor exemplify non-iridescence. Their neutral tone remained consistent, even under varying light sources and different angles of view.
• The surface of the old leather sofa displayed Non-iridescence, maintaining a consistent, worn brown colour, without any hint of shifting colour or interference.
• The plain white wall of the gallery provided a backdrop with Non-iridescence, ensuring that the artwork displayed maintained a consistent color, without any distracting shimmer.
