Well, I can see the problems with the copyright, but I don't understand whats so great about the site... Just add bgcolor="#333333" What's so great about that?.. Now if it were to search all the banded google sites, thats an accomplishment.
Yeah I was about to say that but I didn't want to bash the OP I don't see anything really innovative about it...google themselves redesigns their own logo depending on the season
To avoid infringement, you could spell your site Dar Kgoogle, which clearly isn't using Google . Anway, nice site, g'luck with talking to Google once they find it.
I honestly doubt they are going to sue you because you created a darker version of their website. That would be pretty retarded.
