Specifically, the method includes applying a dark material to at least one of the light-colored substrate and the light-colored translucent overlay upon an area of overlap of the substrate and overlay, and sandwiching the dark material between the overlay and the substrate at the area of overlap so that certain wavelengths of light normally passing through the overlay into the substrate and reflected by the substrate back to and through the overlay are blocked by the dark material. The light-colored overlay in the area of overlap appears in its true light color to the “naked” eye absent the aesthetically unacceptable hue.
