I decided to investigate the Gestalt principles on a few cereal boxes.

 

Closure | Lucky Charms:

• The “charms”cereal pieces form the shape of an arch. This shape is reinforced by the rainbow in the background.

Continuation | Corn Flakes:

• The rooster is glancing toward the top right of the box, guiding our eyes to the cereal brand name.

Symmetry | Mini-Wheats!:

• The flatlay of the cereal bowl circle is perfectly centred on the box. The wheat on the left and cereal pieces on the right of the bowl balance each other.
