For Paul Signac, color was not decoration; it was a method, a rhythm, and a source of light. With Georges Seurat, he helped develop Pointillism and Neo-Impressionism, building images from small touches of pure color.

Signac left architecture for painting when he was young and soon became part of the independent Paris art scene. A sailor as well as an artist, he traveled widely along European coasts, painting ports, rivers, harbors, and bright waterside views.

His legacy is tied not only to his paintings, but also to his role as a champion of modern color theory. Signac helped turn Impressionist spontaneity into a more structured, luminous system that influenced the next generation of artists.
