Synonyms: Law of Closure
The principle of closure states that when we look at a complex group of visual elements, we tend to look for a single and recognizable pattern. The human brain tries to fill in the gaps in order to perceive different objects as a close unit.

The principle of closure is applied in the design of logos. It helps to create interesting and engaging solutions. For example, WWF logo with panda. Yes, we love pandas!
Icons should be simple and understandable to all the users. It is not easy to make a good icon as we have a limited space for them and can not detalise the image. Here the principle of closure helps. We reduce icons to their basic elements and build a composition that helps people to recognize objects.
Make sure that users perceive the elements as a whole. Provide enough information and details
Use positive and negative space. Pay attention to hidden shapes in negative space or within type
Use contrast to shape the closure in your design. Black and white are best for this purpose, but experiment with other colors
If you use simple templates, remove or reduce design elements
If you use complex patterns, use the transition elements to help users to form a pattern
