Disorganized color juxtaposed with uniform shape can show creative thinking in an organized setting, or create a rushed or lax mood depending on the direction of the lines. Circular and asymmetrical shapes can show a disorganized flow of thought, and change the mood of a piece by focusing attention on whatever the circle surrounds or focuses on. The change of dark and light tones can also focus the reader's attention because they will notice the differences in shades and hues, and therefore be kept "on their toes" throughout a presentation.
