Influenced by the introduction of bold and simple collage shapes, Synthetic Cubism moved away from the unified monochrome surfaces of Analytic Cubism to a more direct, colorful and decorative style. Although synthetic cubist images appear more abstract in their use of simplified forms, the other elements of their composition are applied quite traditionally. Interchanging lines, colours, patterns and textures that switch from geometric to freehand, dark to light, positive to negative and plain to patterned, advance and recede in rhythms across the picture plain.
