1. A variable reflectance mirror element, comprising:
a first substantially transparent substrate comprising a first surface and a second surface and an optical thin-film band of material disposed circumferentially at a periphery area of said first substrate so as to match a spectral distribution of ambient light reflected from the periphery area of the first substrate with a spectral distribution of ambient light reflected from inside the periphery area of the first substrate;
a second substantially transparent substrate comprising a third surface and a fourth surface; and
a layer of ruthenium proximate at least one surface selected from the group consisting of said first surface, said second surface, said third surface, and said fourth surface.
