Query: Each pigment an adventure!

Both informative and entertaining, this is a must read for anyone dealing with color. Especially if you need historical background on pigments. I was reading it on a train and the woman sitting next to me asked about it--she is a costume designer and needs historically acurate information on which dyes were available in which period.All those exotic and cryptic names of pigments take on personality and meaning when you read this: rose madder, Prussian blue, burnt sienna. It's as much a travel book as a history. Ms. Finlay has researched and traveled the path of each pigment. She weaves anecdotes with historically based tales to create vivid portraits of the dramatic and highly varied origins of each pigment. Highly recommended.
