A coating includes a functional coating, such as a solar control coating
having at least one metal layer. A topcoat is formed over at least a
portion of the functional coating. The topcoat includes a first topcoat
layer having a thickness in the range of 0.5 QWOT to 1.5 QWOT with
respect to a reference wavelength of 550 nm and a first refractive index,
and a second topcoat layer having a thickness in the range of 0.5 QWOT to
1.5 QWOT with respect to a reference wavelength of 550 nm and a second
refractive index different from the first refractive index.
