Color me (🙄) skeptical on this one:
Import images or photographs into your library. Illustrator will analyze the images in order to extract the color palettes. If there’s a specific palette that you want to try, simply select the image to easily apply the color—you’ll notice that all fill colors in your artwork updates simultaneously.
This all strikes me as eerily reminiscent of the Live Color demos from CS3 10+ years ago (or hey, if you wanna feel even older, remember Adobe Kuler? no, just me?). I don’t doubt that the color remapping work, I just doubt—with extreme prejudice—that any normal humans will know how to take the time to set up these themes in their artwork.
