Moments ago, I finished reading a library book, Color: A Natural History of the Palette by Victoria Finlay. This book preceded the Jewels book by the same author, and she spent her research for it, traveling to many places famed for their pigments and dyes. Reading this book gave me an entirely different outlook on the history of art, and made me think about color in a new way.
I flashed this book Saturday at my sister the artist, who also teaches art, and it's one that she treasures, and I can see why.
If you have any interest in art/dying/painting/art history, I'd recommend reading this book.
