The Secret Language of Color: 06/15/15
The Secret Language of Color by Arielle Eckstut is an exploration of the visible spectrum in human history and in nature. The book is divided by color and by different topics in nature (the universe, earth sciences, plants, and so forth).
It's a concise introduction to color and the various sciences that use and study color. It's an oversize book so a little awkward to read in bed (as I did) but the size allows room for the numerous full color photographs included.
