This book will be very useful to laymen and professionals for use in selection of exterior colors and materials for new houses, remodelings, and even when the house is getting re-painted.
Laymen, when re-doing their own house to whatever degree, would love the book because Ms. Hershman clearly and simply explains her points by use of examples (in beautiful photography) as well as the written word. For professionals, the book offers a collection of images and ideas that can presented to their clients so that they can understand that color is not a "paint job". Rather, exterior color is really an integrated system of materials and colors--and that system can range for the very simple to the very complex.
This book would be wonderful addition to anyone's library.
