A material that creates an iridescent surface with a rainbow reflection effect. The object's color smoothly changes depending on the viewing angle and lighting, simulating the phenomenon of iridescence observed in soap bubbles, oil films, mother-of-pearl, and some metals.

The effect can be applied to any 3D object—from decorative elements to sci-fi materials and stylized surfaces.
