In his iconic Sunflowers series (1887–1889), Vincent van Gogh explored the expressive potential of a single color palette, primarily utilizing varying shades of yellow to convey warmth and vitality. These still lifes depict sunflowers in different stages of their life cycle—from full, radiant blooms to heavy, wilting seed heads—arranged in simple ceramic vases. Using a thick impasto technique, Van Gogh applied paint so heavily that it created a three-dimensional texture, mimicking the rough stalks and fuzzy centers of the flowers. For Van Gogh, the sunflower was a symbol of gratitude and friendship, and the series remains a testament to his ability to find profound emotional depth in a humble, everyday subject.
