How did Pierre-Auguste Renoir use small multicolored brushstrokes in his Impressionist paintings?

Pierre-Auguste Renoir utilized small, multicolored brushstrokes as a fundamental technique to capture the fleeting effects of light and atmosphere in his Impressionist paintings. By applying these discrete flecks and dabs of harmonizing or contrasting colors side by side, he was able to evoke the vibration of the environment, the sparkling quality of foliage, and the luminosity of skin when viewed outdoors.12

This method allowed Renoir to move away from traditional, muted palettes, instead creating light-suffused compositions that avoided the use of black in shadows, which the Impressionists considered inaccurate. Through this technique, the forms in his paintings lost their rigid outlines, appearing to shimmer and vibrate in a recreation of actual outdoor conditions.12

While this approach was central to his work during the height of the Impressionist movement, Renoir eventually felt that these small, multicolored strokes were insufficient for conveying certain textures, such as the satiny effect of skin, leading him to later experiment with more linear and defined styles.3
