For this painting, the two significant principles of design are emphasis and unity. Schiele created emphasis in this artwork by depicting Koller in the middle of the painting as the focal point. Not only the placement, but also the grouping and the contrast. Schiele emphasized Koller by using mostly blue and dark blue on Koller’s clothes and the sofa he sat in to make the center part as a whole group. Also the books in the back and front are around Koller which emphsized Koller as well. By the contrast, Schiele used cool colors on Koller and warm colors on the books and the rug to distinguish Dr. HugoKoller. Plus the book that in Koller’s hands is the only one opens of all the books in the painting. This is a contrast as well. Dr. HugoKoller
