This work is a comprehensive and practice-relevant presentation of color and shape psychology. With clear language and over 100 color illustrations, the complex subject matter is illustrated in a scientific and stimulating manner. Beyond a general introduction to the fundamentals of the visual system, you will also acquire specific knowledge about the associations, effects, and applications of certain colors and shapes. The author places special emphasis on their use in game design. Additionally, a new color study is presented for the first time, demonstrating that the associations with colors can be organized within a logically coherent three-dimensional system. The surprising insights drawn from this provide possible answers to fundamental questions of philosophy. Therefore, the book is not only a must-read for perception psychologists and designers.
