Chevreul’s famous law: “Two adjacent colours, when seen by the eye, will appear as dissimilar as possible”.
Chevreul influenced Impressionists and Cubists: Delaunay, DelaCroix and Seurat.
Artists start liberating color from the form and use it on a non representational way- more subjective and independent from the subject-.
The Fauves- Wild Beasts initiated the first modern color movement. Colors were brighter and unnatural then ever.
