How awesome is this:
For one amazing week in November, Adobe Bookshop in San Francisco has agreed to allow its estimated 20,000 books to be reclassified by color. Shifting from red to orange to yellow to green, the books will follow the spectrum continuously, changing Adobe from a neighborhood bookshop into a magical library—but only for one week.
All I have to say about that is that I'll be there! Finding a book based on color sounds like fate to me.
