On August 21, 2012, Yale University Press, the publisher of The Interaction of Color, sent my host a DMCA takedown notice, which you can read below if you like.
After some deliberation, I've chosen not to contest the notice. Partly this is because of stories like Andy Baio’s and partly because I'd prefer to spend my energy on other projects.
If you’re a professor who was using this site in your course, sorry! I’ve heard rumors of an official CD-ROM, so track that down if you can; otherwise, there's always Color-Aid paper.
