1. A deadfront article comprising:
a substrate comprising:
a first surface; and
a second surface opposite the first surface;
a semi-transparent layer disposed onto at least a first portion of the second surface of the substrate, the semi-transparent layer having a region of a solid color or of a design of two or more colors; and
a contrast layer disposed onto at least a portion of the region, wherein the contrast layer reflects light to enhance visibility of the color of the region or to enhance contrast between the colors of the design of the region on the portion of the region on which the contrast layer is disposed when the deadfront article is not backlit, wherein the contrast layer is white and has a whiteness of 20W or greater as measured according to ISO 11475:2004.
 
15. A device comprising:
a deadfront article comprising:
a substrate;
a semi-transparent layer disposed on a first surface of the substrate layer;
a contrast layer disposed on at least a portion of the semi-transparent layer, wherein the contrast layer reflects light to enhance visibility of a color of the contrast layer when the deadfront article is not backlit; and
a high optical density layer disposed on at least a portion of the contrast layer, the high optical density layer at least in part defining at least one icon; and
a touch panel located behind the at least one icon, the touch panel configured to respond to a touch by a user, wherein the substrate includes a second surface opposite to the first surface such that the first surface and the second surface define a thickness of the substrate layer and wherein a region of the second surface is modified to provide tactile or visual indication of the at least one icon.
