The eye spontaneously groups scattered same-color areas into a visible shape — these 'simultaneous patterns' are independent organizational elements in composition

When the same color (or same level of brightness, texture, or accent) appears in multiple separate locations in a composition, the eye connects them into a perceived configuration — a ‘simultaneous pattern’ — even though this shape is not physically drawn. Itten demonstrates: yellow patches scattered across a picture form a perceived triangle; red patches form a square; blue patches a pentagon. These emergent configurations are a second compositional layer above the literal drawing. Effective composition requires that these simultaneous patterns have clear forms and distinctive spatial positions relative to each other — otherwise their mutual interference creates visual chaos. Codirectionality (parallelism) of color areas is another ordering principle: parallel color zones create coherence across compositional sections without literal repetition.

Examples

In Hydra or p5: scatter yellow elements across the canvas and observe the emergent triangle. In Van Gogh’s Café at Evening: the scattered yellow lanterns form a simultaneous arc that ties the composition together above the blue-black sky.

Assessment

In a composition using five scattered red areas and six scattered blue areas, predict the emergent simultaneous patterns. Explain why all simultaneous patterns in a composition must occupy ‘a distinctive situation relative to each other.’
