A mobile station (10) for receiving and generating wireless communications signals. The mobile station (10) includes layers of translucent materials (15, 16) each having a visual characteristic and overlapping portions that define another visual characteristic. The layers (15, 16) can be used to define keys (12) overlying pressure sensitive regions of a wireless communications signal processing assembly (e.g., dome contacts on a printed wiring board). Keys (12) constructed of two layers have a first and second visual characteristics defined individually by the first and second layers (15, 16) respectively, and a composite visual characteristic defined by the overlapping portions of the layers (15, 16). For instance, the first and second visual characteristics may be two different colors that in the overlapping region form a composite color that is aesthetically attractive and distinguishes that portion of the key for easy identification during use.
