Piet Mondrian's artistic style is distinct for its embrace of geometric abstraction and a strict use of primary colors, particularly red, blue, and yellow. He sought to convey a sense of harmony and balance through the reduction of forms to their essentials, utilizing a grid-like composition. Mondrian's works represent his philosophy of neoplasticism, aiming to express universal beauty through simplicity. This innovative approach had a lasting impact on modern art, influencing various movements such as minimalism and abstract expressionism. Mondrian's pursuit of pure expression through geometric forms remains a significant contribution to the art world.
