Here are the several faces of the Kuler Dashboard Widget. Just downloaded it a few days ago and it’s very useful for a quick look into kuler color schemes and a link to the scheme page on the kuler site. You can do that, search the most popular and have the HEX values of the colors on that scheme as you can see ini the screenshot below. The wallpaper I’m using is Galactic Barrier Alt – by Dave Brasgalla, which you can find in the Iconfactory site.
