Here's a pretty cool tool for all of you graphic designers and art directors out there. It's called ColorJack, and it's a simple color sphere that matches up colors that work well together. It's got a few settings you can play with, like choosing how you many colors you want in the scheme, or how you want them to work together. You can also export the swatches to programs such as Illustrator and Photoshop. Great for an easy color scheme to your next project. There is also a Mac OSX widget version.
