The invention provides improved solution-phase electrochromic devices, wherein the solution of reversibly variable transmittance is tinted with a tint-providing compound, and solutions of reversibly variable transmittance for use in the improved devices of the invention. An electrochromic device of the invention can be used, for example, as the component of reversibly variable transmittance in a variable-reflectance motor vehicle mirror. Among such mirrors provided by the invention are blue-tinted mirrors. |
