Piet Mondrian was a pioneer of abstract art, known for his distinctive style characterized by geometric shapes, particularly rectangles and squares, and a limited palette of primary colors (red, blue, and yellow) along with black and white. He was a key figure in the De Stijl movement, which emphasized simplicity and harmony through abstraction. Mondrian's work focused on the balance and relationships between colors and forms, aiming to express universal beauty and order. His iconic grid compositions have had a lasting influence on modern art and design.
