Query: Disappointed by the color and the works not the concept

I was most disappointed by the lack of color in the book and by the style and nature of Curtis' paintings. There is a collection of color plates in the center of the book, but unfortunately they didn't relate to the sections I was interested in. Curtis' method probably makes sense but with so many of the illustrations in b&w and the works uninteresting I just couldn't get into it.
