Divisionism, also known as Pointillism, is a painting technique developed by Neo-Impressionist artists in the late 19th century. It involves applying small, distinct dots or strokes of pure color to the canvas. These dots are placed close together, allowing the viewer's eyes to blend them optically and perceive a broader range of hues and tones. Divisionism aims to create luminosity, depth, and vibrancy, resulting in vibrant and dynamic compositions that shimmer with light and energy.
