Art Nouveau's influence on modern art can be seen in the emergence of new design styles, such as Art Deco and Modernism. These styles incorporated Art Nouveau's organic forms and intricate details into their designs, while also adding their own unique elements. For example, Art Deco emphasized geometric shapes and bold colors, while Modernism focused on simplicity and functionality.

Art Nouveau's influence on modern art can still be seen in contemporary design. Many designers continue to incorporate the movement's organic forms and flowing lines into their work, creating a modern aesthetic that pays homage to the past. For example, the work of designer Philippe Starck often features Art Nouveau-inspired elements, such as curved lines and floral motifs.
