This little site is a nice example of how to do a dark-colored site using bright colors for highlight. I really like the idea of highlighting certain info with a solid background color similar to the rollovers of my links. Best of all, the site is a single page. Straight and to the point.
Circle Six uses a killer color combination of orange and blue. I really like the logo which plays with depth by wrapping through the logo and on top of and over the orange nav bar. I’m not a big fan of the fluff at the bottom. The best thing has to be the Twitter status which fades in both size and color as the updates age.
