Another term for asymmetrical balance is informal balance.
Asymmetrical balance refers to a design or composition where the elements on either side of a central axis are not identical, but still create a sense of harmony and balance. This is achieved through the arrangement of different shapes, colors, and sizes in a way that feels visually stable. Informal balance often creates a more dynamic and interesting composition compared to its symmetrical counterpart, appealing to the human eye through contrast and variation.
