How did Vincent van Gogh use color and thick paint in Sunflowers?

In his iconic Sunflowers series, Vincent van Gogh utilized his signature style to transform simple subjects into vibrant expressions of form and light.

He employed a technique known as impasto, where paint is applied so thickly that it stands out from the canvas surface. By using these thick, nervous dabs of paint, he was able to build up the physical texture of the sunflowers, giving them a tangible, three-dimensional quality that defined their forms.1

Complementing this heavy application of paint was his use of striking color, a hallmark of his work as a Post-Impressionist. Van Gogh’s deliberate choice of intense, bold hues allowed him to capture the essence of the flowers with an emotional intensity that moved beyond mere representation, ultimately influencing the development of Expressionism. Through this combination of heavy texture and vivid color, he created works that emphasized the physical qualities of the paint itself.21
