摘要： The present invention is directed to a chromatic effect light reflective unit (1; 1a-1g). The unit (1; 1a-1g) comprises a reflective layer (10) having at least one reflective surface (11), and a chromatic diffusion layer (20) having a first surface (21) proximal to the reflective surface (11) and a second surface (23), opposite and substantially parallel to the first, configured to be illuminated by incident light, wherein the chromatic diffusion layer (20) comprises a nano-pillar (70) or nano-pore (30) structure in a first material having a first refractive index (n1), immersed in a second material having a second refractive index (n2) other than the first (n1), in which the first and second materials are substantially non-absorbing or transparent to electromagnetic radiations with wavelength included in the visible spectrum, wherein the ratio (nM/nm) between a higher refractive index (nM) and a lower refractive index (nM) chosen between the first (n1) and the second (n2) refractive indexes is comprised between 1.05 and 3, wherein the nano- pillars (71) or nano-pores (31) have a development along a main direction not parallel to the first surface (21) and the second surface (23) of the chromatic diffusion layer and the nano- pillars (70) or nano-pores (30) structure is characterized by a plurality of geometric parameters comprising a pillar diameter or pore diameter (dp), a pillar length or pore length (1p) along said main development direction, and a surface density of nano-pillars or nano-pores (Dp) and/or a structure (30,70) porosity (Pp) and wherein the pillar diameter or pore diameter (dp) is comprised between 40 nm and 300 nm, the length (lp) along the main development direction is comprised between 300 nm and 40 µm (300 nm
