His famous series, such as Water Lilies and Haystacks, showcased his mastery of color and brushwork. Monet's innovative approach to painting, characterized by loose brushstrokes and an emphasis on capturing the essence of a scene, revolutionized the art world and laid the foundation for modern art.
