Final answer:
Georges Seurat used the technique of pointillism, painting with tiny dots of pure color that blend at a viewing distance, in his masterpiece, A Sunday Afternoon on the Island of La Grande Jatte.
Step-by-step explanation:
To ensure that his experiments with color worked correctly in A Sunday Afternoon on the Island of La Grande Jatte, Georges Seurat painted dots around the edges of the painting using the same pointillism technique. Georges Seurat developed a technique of painting with tiny colored dots called Pointillism as he branched out from Impressionism. This technique relies on small dots of color that blend in the viewer's mind, creating a large scene.
Up close, each dot might seem isolated, but when viewed from a distance, the image becomes cohesive and lifelike.
Seurat's innovative approach was based on his studies of color theory, which he transformed into his method called "pointillism." He thought that by placing small dabs of pure color next to each other they would mix in the viewer's eye, thus creating the desired light and shadow effects, as well as harmony and emotion in the painting.
Moreover, Seurat's work contrasted with that of the Impressionists through the defined lines between figures and backgrounds achieved by his dot technique, where others termed it Pointillism, though he preferred the term Divisionism.
The large scale piece, A Sunday Afternoon on the Island of La Grande Jatte, is a prime example of how the application of systematic dots of color can create form and structure, forever immobilizing the figures in a sensation of silent stillness.
