Final answer:
Van Gogh's use of oil paint created texture, depth, and nuanced color in his paintings.
Step-by-step explanation:
Van Gogh's use of oil paint had a significant impact on the effect of his paintings. One important quality of oil paint is its ability to be built up in thick layers called impasto, which creates texture and depth in the artwork. Van Gogh often used impasto techniques to emphasize certain elements of his paintings, such as the texture of the coat or the threads of a bandage. Additionally, oil paint has a slow drying time, allowing for blending and adjustments to be made, resulting in nuanced color and shading in Van Gogh's works.
