I've recently gotten into microhistories, and came across this one in a list of Best Microhistories. I purchased it on a whim, and happily, it did not disappoint. The book started life as a series of magazine columns, and the style - easy to read, presenting interesting information in neat, engaging bite-sized pieces - has been carried over to the book nicely. St Clair provides one or two interesting things about each colour, for some it might be how the dye/pigment is produced, for some a historical figure or time period or artist it's particularly associated with, etc, with most entries ranging from one and a half to three or four pages long. It's very much the kind of book you dip into, as the mood takes. Lastly, I love that in the paperback, the colour under discussion is printed in a strip down the side of the page, so that a) you get a visual of the colour, and b) the book looks beautiful.
