Abstract: A dead front panel for an electronic device includes a transparent substrate and a layer of colorant. The transparent substrate corresponds to a surface of the electronic device and has a display window area and a non-display window area. The display window area is an area through which light is emitted by a display element of the electronic device when the display element is illuminated. The layer of colorant is applied to a back surface of the transparent substrate at both the display window area and the non-display window area. A thickness of the layer in combination with a transmittance of the colorant permits visibility of the light emitted by the display element when illuminated and obfuscates visibility of the display element when not illuminated.
