What was the importance of color to Robert delaunay?

Robert Delaunay believed that color was of the utmost importance in expressing emotions and sensations, and he strived to liberate color from its traditional descriptive function and instead use it to create dynamic and abstract compositions that conveyed a sense of movement and light. He was particularly drawn to the effects of simultaneous contrast, which occurs when two adjacent colors of high intensity create an optical vibration or shimmering effect.

Delaunay's fascination with color led him to develop his signature style of Orphism, which emphasized the interplay of pure, saturated colors and geometric forms. He sought to create a visual experience that was not tied to the representation of objects but rather focused on the inherent qualities of color and its ability to evoke emotions and states of mind. Through his experiments with color, Delaunay pushed the boundaries of abstract art and helped to establish the importance of color as a central element in modern painting.
