A vehicular trim component comprises a substrate having external and internal surfaces and a finish on at least one of the external and internal surfaces. An illumination source actuatable between an illuminated state and a non-illuminated state is positioned behind the substrate to direct light through the finish with the illumination source is in the illuminated state. A mask associated with the substrate defines at least a masked portion and an unmasked portion, wherein the unmasked portion transmits more light than the unmasked portion. The finish extends across both the masked portion and the unmasked portion to conceal visible differences between the masked portion and the unmasked portion when the illumination source is in the non-illuminated state. When the illumination source is in the illuminated state, light passes through the unmasked portion and the finish to provide a visible distinction between the masked portion and the unmasked portion.
