Abstract
A device for displaying images having variable colors comprises a substrate; a light-transmissive coloring layer painted or laminated on the substrate, the coloring layer comprising colorants of different colors and having a rear side in contact with the substrate and a varnished front side; a display layer comprising a silvering material directly plated on the varnished front side of the coloring layer, the display layer comprising a display pattern forming a visible displayed image, the silvering material comprising a metal, a metalloid, or an oxide thereof to form a one-way-mirror; an illuminator configured and positioned to illuminate the coloring layer from the rear side of the coloring layer. When the coloring layer is unilluminated by the illuminator, the unilluminated coloring layer is hidden behind the one-way-mirror. When the coloring layer is illuminated by the illuminator, the illuminated coloring layer visibly colorizes the displayed image through the one-way-mirror.
