Unity Principle
Unity principle is about harmonizing the design of an interface. All the elements present in the design should be visually and logically harmonized. Harmonizing all the colors, shapes, images, texts, dividers, textures, etc to make the design look visually appealing and logically correct is part of the Unity Principle. All these small factors make the design look good on an overall interface. The elements that are present in the interface should complement each other by making the important components stand out.
