While browsing the unwanted books section at a local thrift store, I came across an amazing item: The Elements of Color by Johannes Itten. The book's subtitle is "A treatise on the color system of Johannes Itten based on his book The Art of Color," and the contents are full of beautiful diagrams and fascinating (if a tiny bit overblown) writing on the practice and history of color theory. It was definitely worth the $2.99 spent. I adapted some of the figures within the book for this comic. I loved the way Itten wrote of the colors as if they were living, breathing entities, with the capacity for good - or evil.You can order a poster here.
