I agree, the new colors do brighten things up & looks more modern.  But in a bright office I could see where it might be difficult to view.  I think you can set your browser to view pages in your own color scheme, I believe you can set it in Internet Options, but someone may correct me on that point.  I remember reading it somewhere, but haven't bothered to do so myself.

Anyway cool new look, hats off to your dedication to the site!!
