Design Theory is a framework that explores the principles and processes involved in creating effective designs. It encompasses various disciplines, including graphic design, industrial design, and architecture, focusing on how elements like color, shape, and texture can be combined to achieve specific goals. The theory emphasizes the importance of user experience and functionality in the design process. At its core, Design Theory seeks to understand how design impacts perception and behavior. It draws on concepts from psychology and aesthetics to inform decisions, ensuring that designs are not only visually appealing but also practical and user-friendly. This approach is essential for creating products that resonate with users and fulfill their needs.
