Architecture is a combination of art and science. It defines the design and construction of spatial structures such as artifacts and site buildings. Design theory, a combination of various design principles, helps graphic designers to use various elements in images such as patterns, symmetry, and colors effectively. It helps the audience to grasp the exact message that the designer wants to communicate. Design theory mainly includes five principles namely alignment, contrast, repetition, balance, and hierarchy. And it can be wisely used by learning the color theory and researching the graphic elements.
