How did Georges Seurat’s pointillism influence Vincent van Gogh?

Georges Seurat’s pointillism—a technique involving the systematic application of small dots of pure color—influenced Vincent van Gogh during his time in Paris between 1886 and 1888.123

After being introduced to Seurat and other Impressionist artists by his brother Theo, van Gogh began to experiment with these new methods. By the summer of 1887, he was incorporating pure colors and broken brushwork that was at times pointillistic into his own paintings.3

While Seurat used this theoretical technique to achieve luminosity through optical blending, van Gogh adapted these lessons to develop his own personal idiom. He ultimately transformed the contrasting, short brushstrokes of the Impressionist and Neo-Impressionist styles into the curving, vibrant lines of color that characterize his later, emotionally charged work.23
