1. An opaque article, comprising:
a stack of layers including a high refractive index layer and a low refractive index layer;
wherein at least one layer of the stack includes a wavelength selective absorbing material; and
wherein the stack of layers has a transparent region with an edge at a wavelength in which light is absorbed by the wavelength selective absorbing material, and a reflection band with an edge at a wavelength in which light is reflected by the wavelength selective absorbing material,
wherein the stack does not include a layer of metal.
