The book has over 450 images. In the black and white edition, all of the images are in grayscale. The Revit interface makes use of color in the interface elements, sketch modes, shaded displays and materials. In the color edition, all of the color is preserved and the images in the book match much more closely what you will actually see on your Revit screen. Furthermore, the color edition uses nicer weight paper with a smoother finish than the black and white edition. Naturally printing a book of this size in full color is more costly, but the quality of the final product is well worth the price.
