Here's a neat site for the designers & art directors out there: Brand Colors. At a glance see what Dribbble, Dropbox, Coca Cola, Adobe, Dell, Flickr and Flattr have as their brand colors. You can download the colors as CSS, LESS, SCSS or ACE. You can sort the colors in collections, like music and photography. The only thing that would make this better if you could submit a color palette and automagically turn that into downloadable css. That would be magic. Our brand colors above, are not listed on the site... Yet. ;)
