A simple hint for reference: Van Gogh is a representative figure of 19 th century post-impressionism. He is especially good at dealing with bright colors in the sun. He seems to be an artist born for the pursuit of sunshine. In his representative work > In fact, this kind of understanding and enthusiastic pursuit of sunshine fully shows that Van Gogh once wrote in a painting in memory of his cousin: "As long as the living are alive, the dead will live forever." Facing the dense flowers that thrive in the sunshine, this "sun of the earth" is precisely his symbolic love and pursuit of life. Sunflowers on the screen are not only full of bright colors in the sun, but also seem to be burning with vitality and artistic emotion, which is a transparent, brilliant and vigorous life essence. Before that, no painter could make people feel that life is so warm and powerful in the picture. Under the artist's creative consciousness, the branches and leaves of sunflower are also deliberately distorted and full of power, making the whole picture very infectious. It is worth mentioning that: from a historical perspective, the consciousness of> was quite advanced in Europe at that time. Because of religion (Judas, who betrayed Jesus, likes to wear yellow clothes), the yellow tone is regarded as a low tone, which is difficult to be elegant. Van Gogh uses this color extensively in the whole picture, and uses a small amount of dark red and green to contrast the main color of bright yellow, making the picture more dazzling and brilliant. So this work became a classic of impressionism and was brought by later impressionists.
