More Information
Summary:The invention relates to a chroma effect light reflecting unit (1; 1a-1 g). The unit (1; 1a-1g) comprises a reflective layer (10) having at least one reflective surface (11); and a chroma diffusing layer (20) having a first surface (21) close to the reflective surface (11) and a second surface (23) opposite and substantially parallel to the first surface, configured to be irradiated by incident light; wherein the chroma diffusing layer (20) comprises a structure of nanopillars (70) or nanopores (30) made of a first material having a first refractive index (n1) immersed in a second material having a second refractive index (n2), the second refractive index (n2) being different from the first refractive index (n1), and wherein the first material and the second material are substantially non-absorbing or transparent to electromagnetic radiation having a wavelength comprised in the visible spectrum; wherein the ratio (nM/nm) between the higher refractive index (nM) and the lower refractive index (nm) selected bet
