Final answer:
The color research influencing Impressionist and Post-Impressionist artists came from the scientific study of color theory, not directly from another artist. Figures like Vincent van Gogh and Claude Monet were practitioners, not the researchers influencing others. Instead, scientists like Michel-Eugène Chevreul provided the insights that affected these art movements.
Step-by-step explanation:
The color research that influenced many of the Impressionist and Post-Impressionist artists was not the direct work of another painter, but rather the study of color theory from scientific principles that emerged during the 19th century. These theories delved into how colors are seen and combined, which provided a basis for artists to explore color in new ways. When considering the options provided: a. Vincent van Gogh, b. Pablo Picasso, c. Claude Monet, d. Wassily Kandinsky, none of these artists are primarily known for their color research influencing others. Instead, they were influenced by prior research on color. Thus, the question as stated does not point to a correct option, as artists like van Gogh and Monet were themselves part of these movements, and their work was influenced by the principles of color theory explored during that time.
Artists like van Gogh, Gauguin, Seurat, and Cézanne developed new approaches to using color, often employing it to express emotion and abstract concepts rather than simply replicate the natural world. The color experiments by these Post-Impressionists in turn influenced later movements, such as Expressionism.
The actual color theory research that influenced these artists could be attributed to scientists such as Michel-Eugène Chevreul and others, whose work delved into complementary colors and contrasts, and which had substantial impacts on artists during the Impressionist period and beyond.
