Every art form had its own unique expression and aesthetic characteristics. Different artists would have different styles and creative ideas. In the art of painting, modeling was a very important part.

Color was also a very important element in painting. Colors could bring emotions and atmosphere to a work. Different colors and combinations could also create different effects and styles. Artists needed to express their inner feelings and aesthetic concepts through the use of color. In the process of painting, the artist also needed to pay attention to the composition and the variety of expression techniques. The composition could be arranged, combined, and seen through to create different visual effects. The expression techniques could also use different techniques and means such as light and shadow, lines, and texture to create a richer and more vivid work.
