Because theories of visual perception have traditionally concentrated on form, artists have generally dealt with the problem of color through their own observation and intuition. In Color Harmonies, Augusto Garau systematically investigates the role of both color and form in visual perception and presents an original theory of the aesthetic relations among colors.

Garau, a painter who teaches the psychology of form, pays particular attention to the way colors behave when organized in patterns. His theory of color combination addresses two principal compositional elements: the relations between figure and ground and the phenomenon of transparency.

Garau meticulously analyzes the use of color in paintings by masters such as Cézanne, Picasso, and Matisse to show how his theory applies to actual works of art. Containing many full-color examples, his introduction to the workings of color relations is of great practical use to art historians and critics, artists, interior decorators, fashion and set designers, and anyone who works with color to display information or convey emotions.

"In an area of the psychology of art where reliable guidance is still so hard to come by, [Garau's] well-supported contributions to the theory of color composition ought to be welcomed by practitioners and scholars alike."—from the Foreword by Rudolf Arnheim

A committed Lutheran excommunicated from his own church, a friend to Catholics and Calvinists alike, a layman who called himself a “priest of God,” a Copernican in a world where Ptolemy still reigned, a man who argued at the same time for the superiority of one truth and the need for many truths to coexist—German astronomer Johannes Kepler was, to say the least, a complicated figure. With The Pursuit of Harmony, Aviva Rothman offers a new view of him and his achievements, one that presents them as a story of Kepler’s attempts to bring different, even opposing ideas and circumstances into harmony.
 
Harmony, Rothman shows, was both the intellectual bedrock for and the primary goal of Kepler’s disparate endeavors. But it was also an elusive goal amid the deteriorating conditions of his world, as the political order crumbled and religious war raged. In the face of that devastation, Kepler’s hopes for his theories changed: whereas he had originally looked for a unifying approach to truth, he began instead to emphasize harmony as the peaceful coexistence of different views, one that could be fueled by the fundamentally nonpartisan discipline of mathematics.
