1. An electrochromic system comprising:

  • an electrochromic element comprising;

    a front element comprising first and second surfaces;

    a transparent electrode on said second surface;

    a rear element comprising third and fourth surfaces, wherein said front and rear elements are sealably bonded together in a spaced-apart relationship to define a chamber, such that said second surface and said third surface face one another; and

    an electrochromic medium contained in said chamber, wherein said electrochromic medium is adapted to be in at least a high transmittance state and a low transmittance state,wherein light passing through said electrochromic element has at least a first primary and a second primary, and said first and said second primaries each have a first hue (hab) when passing through said electrochromic medium in said high transmittance state and a second hue (hab

    ) when passing through said electrochromic element in approximately said low transmittance state, wherein a change in said first and second hues (Δ

    hab) for both said first and second primaries is less than approximately 31 degrees,wherein a ratio of intensities of said first and second primaries remains approximately constant.
