What pair of painters responded to the impressionist style by seeking more intense expressiveness of color and design?

The pair of painters who responded to the Impressionist style by seeking more intense expressiveness of color and design are Vincent Van Gogh and Paul Gauguin. Both artists moved beyond the naturalistic approach of Impressionism to explore bold colors and emotional depth in their works. Van Gogh's swirling brushstrokes and vibrant palettes, along with Gauguin's use of symbolism and exotic color schemes, exemplify this shift towards greater expressiveness. Their contributions laid the groundwork for subsequent movements like Post-Impressionism and Fauvism.
