"Untitled" (1979) by Joan Mitchell on display at the "Painting From Nature" exhibition at Espace Louis Vuitton in Beijing, June 6, 2025. The monumental triptych saturates the viewer in a vibrant summer yellow, balanced by hints of purple that bloom across its length. With a rhythm driven by energy and economy, Mitchell channels an internalized vision of nature into her dynamic abstraction. [Photo by Liu Ziying/China.org.cn]
