Vehicle appliques

A vehicle, comprising:

• a window;
• and
• an applique coupled to the window, wherein the applique includes:
• a base structure coupled to a surface of the window;
• a polymeric coating disposed on the base structure, wherein the polymeric coating at least partially covers an outer surface of the base structure, wherein the polymeric coating 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
• a diffraction grating integrally defined by the polymeric coating, wherein the diffraction grating has a thickness in a range of from about 100 nm to about 300 nm, and wherein at least a portion of the diffraction grating has a blaze angle of at least 15 degrees.
