Exploration of the Expression of Color Emotion in Oil Painting Sketch Creation

This paper deeply analyzes the expression of color emotion in oil painting sketch creation. Starting with the three basic attributes of color theory (hue, lightness, and purity), this paper discusses its emotional symbolic significance and the relationship between contrast and harmony. By interpreting the works of artists such as Van Gogh’s Sunflower, Monet’s Rouen Cathedral, and Cézanne’s Mont Sainte-Victoire, this paper shows the unique charm of different colors in conveying emotions, creating atmosphere, and expressing themes. At the same time, it is expounded that in the creation of an oil painting sketch, the effective expression of color emotion can be realized by observing nature, using subjective colors, and reasonable composition and layout of colors, so as to enhance the artistic value of the works.
