Goethe’s Theory of Colors, published in 1810, and Michel Eugène Chevreul’s On the Law of Simultaneous Contrast of Colors, published in 1839, had a huge impact on many generations of artists. Did you notice that these color theories are presented in colorful round shapes? Artists Sonia and Robert Delaunay applied them in many of their works to convey the spinning movement of carousels, Ferris wheels, and even propellers.
