shape - square

A square feels stable.

The eye keeps moving around the shape.

It is balanced and equal.

Even when it becomes a rectangle it is still balanced on each side - with emphasis on the longer lines.

There are horizontal (relaxing lines) and vertical (ready for action) lines.

There are no diagonal or curved lines indicating movement.

USING SQUARE IN AN ENVIRONMENT:

Will make for an ordered environment.

It will indicate formality. It works well as a floor pattern (tiles) as it visually depicts stability.

Because blue is a stable, dependable colour, we think that blue is the ideal colour to represent the emotional response to a square!

They both are the most popular used design elements.
