1. A rearview mirror assembly for use in a vehicle, comprising:
- a first substantially transparent substrate and a second substrate secured in a spaced apart relationship with respect to one another to form a chamber there between, said second substrate comprising two or more layers disposed on a surface of said second substrate closest to said first substantially transparent substrate, said two or more layers comprising a layer of reflective material comprising silver and a first layer of substantially transparent conductive material less than approximately 300 Å
comprising indium tin oxide located within said two or more layers at a location that is closer to said first substrate than said layer of reflective material, wherein the rearview mirror assembly is configured to have a b* value of less than approximately 15 and a C* value of less than approximately 20, the rearview mirror assembly is further configured to have a reflectivity of at least approximately 35 percent, and a transmittance of at least approximately 5 percent.

Abstract
According to one embodiment of the present invention, an electrochromic rearview mirror assembly for a vehicle includes an electrochromic mirror having a variable reflectivity, a glare sensor for sensing levels of light directed towards the front element from the rear of the vehicle, an ambient sensor for sensing levels of ambient light, a display positioned behind the partially transmissive, partially reflective portion of the reflector for displaying information therethrough.
