Structural colours have drawn wide attention for their potential as a futureprinting technology for various applications, ranging from biomimetic tissuesto adaptive camouflage materials. However, an efficient approach to realiserobust colours with a scalable fabrication technique is still lacking,hampering the realisation of practical applications with this platform. Here wedevelop a new approach based on large scale network metamaterials, whichcombine dealloyed subwavelength structures at the nanoscale with loss-less,ultra-thin dielectrics coatings. By using theory and experiments, we show howsub-wavelength dielectric coatings control a mechanism of resonant lightcoupling with epsilon-near-zero (ENZ) regions generated in the metallicnetwork, manifesting the formation of highly saturated structural colours thatcover a wide portion of the spectrum. Ellipsometry measurements report theefficient observation of these colours even at angles of $70$ degrees. Thenetwork-like architecture of these nanomaterials allows for high mechanicalresistance, which is quantified in a series of nano-scratch tests. With suchremarkable properties, these metastructures represent a robust designtechnology for real-world, large scale commercial applications.
