Abstract
Commercial paints have issues with toxicity, environmental instability, and low resolution. Researchers have proposed nanostructured materials as eco-friendly coloration alternatives. However, existing demonstrations face challenges such as sensitivity to angles, polarizations, limited saturation, and impractical industrial integration. We present a self-standing structural coloration approach that exploits plasmonic resonances to produce a comprehensive color range, providing a vivid and rich palette, with angle and polarization independence. Our ultralight paint, weighing only 0.4 g/m2, is fabricated through large-scale techniques, bridging the gap to real-world industrial applications for non-toxic, fade-resistant, and environmentally friendly structural color.
