"Summer, Dune in Zeeland" (1910) is a painting by Piet Mondrian that uses a simplified palette of blues and yellows to depict the Dutch coastline. Created during his Fauvist phase, the work features a vast blue sky above a dune simplified into distinct shapes of yellow and blue, evoking a sense of peaceful vastness and light. It represents an earlier, more naturalistic style compared to his later, more abstract geometric work.
