Final answer:
Georges Seurat developed Pointillism, a technique using small dots of pure color that blend optically to form images with emotional effect and nuanced shading.
Step-by-step explanation:
Georges Seurat, a pioneer of the Pointillism technique, created artworks composed of tiny dots of color. This method, which is also referred to as divisionism or neoimpressionism, allows colors to optically blend when viewed from a distance, resulting in nuanced shades and tones without pre-mixing them on the palette. A celebrated example of this technique is Seurat's masterpiece, A Sunday Afternoon on the Island of La Grande Jatte. Seurat's technique also explores the emotional effects of colors and how their juxtaposition can alter the perception of their intensity. For instance, in his painting Young Woman Powdering Herself, different tones of blue next to each other enhance the illusion of shadow and depth.
