welcome to my latest addiction: kuler. it's a web-hosted application for generating color themes to help inspire projects of all sorts! no matter what you're working on (illustrations, blog posts, paintings), you can quickly upload a photo and experiment with color variations or even browse thousands of themes from other kuler members.
and its even 'cooler' if you work with adobe illustrator! you can save color themes to use in illustrator, or just open the extension (located under window > extensions > kuler) and search right from the desktop. if you itching to share yours, feel free to add them to the ghtr flickr album!
