1. A method of manufacturing a vehicle applique, comprising:
molding a base structure;
nano-engraving a surface of a mold to define a pattern that forms a diffraction grating having a thickness in a range of between 100 nm to 300 nm, wherein at least a portion of the diffraction grating has a blaze angle of at least 15 degrees;
heating the mold;
injecting a polymeric material in the mold over the base structure to form a polymeric coating that includes the diffraction grating and that is optically clear for transmission of visible light having a wavelength between 400 nm and 700 nm and has a haze of 10% or less; and
curing the polymeric coating.
