color coded book spines

San Francisco artist Chris Cobb imagined a library organized by color rather than genre, author or title. The alphabet gives way to a spectrum of light, and as a result, bookstore browsers discover color connections between mysteries and pulp and metaphysics, all on the same-hued shelf. At the Adobe Book Store in San Francisco's Mission District, (for a limited time, perhaps), you'll find used books by happenstance -- or affinity with warm or cool or hot pink book jackets.
