Reductionism in ART and Brain Science, by Eric Kandel, page 143, Zettel 132

Modern abstract art was predicated on two major advances: the liberation of form and the liberation of color. The Cubists, led by Georges Braque and Pablo Picasso, liberated form. Since then, modern art has often represented the artist’s subjective vision and state of mind rather than a naturalistic illusion of form based on the outside world. In the modern era it was largely Henri Matisse who liberated color, freeing it from form and thereby demonstrating that colors and color combinations can exert unexpectedly profound emotional effects. Once color was no longer determined by form, a color that might have seemed “wrong” in a particular figurative context would actually be right, because it was used to convey the artist’s inner vision, not to represent a particular object. Moreover, the separation of color from form is consistent with what we know about the anatomy and physiology of the prime visual system: That is form, color, movement, and depth are analyzed separately in the cerebral cortex. - Reductionism in ART and Brain Science, by Eric Kandel, page 143, Zettel 132

In focusing on color, Rothko was searching for a new style of abstraction that would link modern art forms that reach out to the infinite. To achieve this, he abandoned figuration and focused exclusively on the expressive power of large fields of color. His experiments inspired a number of artists to follow his lead, to free color from objective contexts, inhibit access to figurative associations, and make it a subject of its own.  In a way, Rothko succeeded in achieving what biologists, including biologists of perception and memory, try to do with reductionist science. - Reductionism in Art and Brain Science, by Erick Kandel page 130, Zettel 128
