1. An electrochromic window assembly comprising:
- first and second spaced transparent substrates defining a chamber therebetween, at least one of said first and second transparent substrates having a first color with a first hue angle; and
an electrochromic medium contained in said chamber, said electrochromic medium including at least one dye defining a second color in an electrochemically activated state upon application of electrical potential selected from colors having a second hue angle ranging from said first hue angle plus 45°
to said first hue angle minus 45°

Abstract
The present invention provides an electrochromic window assembly having coloration associated therewith. The assembly includes an electrochromic device defined by two transparent substrates defining a chamber therebetween, and an electrochromic medium including at least one dye contained within the chamber. At least one of the two substrates has a color. The at least one dye also has a color, which either coordinates with the color of the at least one substrate to produce a window assembly of a desired color, or which complements the color of the at least one substrate.
