How do artists replicate the iridescence of fish scales using PVC films?

Artists achieve the mesmerizing iridescence of fish scales using PVC films by mimicking nature’s structural color techniques. The process involves layering thin PVC films to create light-diffracting surfaces that shift hues with viewing angles. By carefully manipulating film thickness and texture, artists replicate the microscopic ridges found in fish scales, which scatter light to produce vibrant, shifting colors. Advanced methods include embossing or coating films with metallic or pearlescent finishes to enhance the effect. This innovative approach allows for sustainable, customizable iridescence in art and design, bridging science and creativity.
