A single-substrate mirror element defined by a transflective metal layer—non-metal layer—metal layer coating disposed on the first surface of the substrate and enabled to meet the requirements of operation in an exterior rearview assembly and to provide for stealthy appearance of a light source of the assembly disposed behind the mirror element. The appearance of the mirror element, defined in parameters of the CIELAB color system, is substantially color-neutral, while tuning of reflectance and transmittance characteristics can be achieved substantially independently from one another. Reflectance value and measure of color content of light specularly reflected by the mirror at non-zero angles remains substantially stable within wide range of angles.
